parameters for dependency build - rust

Suppose I want to install the following dependency in my project:
[dependencies]
multi-party-ecdsa = { git = "https://github.com/ZenGo-X/multi-party-ecdsa.git", rev =
"3e711c792db06aaeeac5694b137d24f7551069d1"}
which builds it with cargo build command.
I would like this instead: cargo build --no-default-features --features curv-kzen/num-bigint. Is it possible without doing it manually?

[dependencies]
multi-party-ecdsa = { git = "https://github.com/zengo-x/multi-party-ecdsa.git", rev = "3e711c792db06aaeeac5694b137d24f7551069d1", default-features = false }
curv-kzen = { version = "*", default-features = false, features = ["num-bigint"] }
This should work.

Getting dependency error in rust Cargo.toml

I am getting some dependencies version errors in rust.
I am fairly new to rust so I do not have any idea how to check for compatible updates between multiple dependencies.
It will be great if someone can resolve this issue and let me know how to manage dependencies.
Cargo.toml:
[package]
name = "chatbot"
version = "0.2.3"
authors = ["Joe Wilm <joe#jwilm.com>"]
license = "MIT"
description = "An extensible chatbot"
documentation = "https://docs.rs/chatbot"
repository = "https://github.com/jwilm/chatbot"
keywords = ["chat", "bot", "extensible"]
readme = "README.md"
[package.metadata.docs.rs]
all-features = true
[dependencies]
regex = "0.1"
rustc-serialize = "0.3"
getopts = "0.2"
irc = { version = "0.12", optional = true }
slack = { version = "0.18.0", optional = true }
[features]
default = []
irc-adapter = ["irc"]
slack-adapter = ["slack"]
I tried with versions suggested by VS Code but it did not work.
Error which I am getting after I do cargo-run is:
failed to select a version for the requirement `security-framework
= "^0.1.13"`
candidate versions found which didn't match: 2.8.2, 2.8.1, 2.8.0, ...
location searched: crates.io index
required by package `native-tls v0.1.2`
... which satisfies dependency `native-tls = "^0.1.2"` of package `tungstenite v0.2.0`
... which satisfies dependency `tungstenite = "^0.2.0"` of package `slack v0.18.0`
... which satisfies dependency `slack = "^0.18.0"` of package `chatbot v0.2.3
You are using old versions of the slack and irc crates. Both depend on an old version of native-tls (v0.1) in their dependency trees. native-tls v0.1 depends on a very old version of the security-framework crate (v0.1). All versions of security-framework v0.1 have been yanked from crates.io, see here: https://crates.io/crates/security-framework/versions. I assume this is due to a security issue in those versions. Because the v0.1 version of security-framework is yanked, you can't download it from crates.io anymore, causing the dependency error during compilation.
You can fix this by updating your irc and slack dependencies to their latest versions:
[package]
name = "chatbot"
version = "0.2.3"
authors = ["Joe Wilm <joe#jwilm.com>"]
license = "MIT"
description = "An extensible chatbot"
documentation = "https://docs.rs/chatbot"
repository = "https://github.com/jwilm/chatbot"
keywords = ["chat", "bot", "extensible"]
readme = "README.md"
[package.metadata.docs.rs]
all-features = true
[dependencies]
regex = "0.1"
rustc-serialize = "0.3"
getopts = "0.2"
irc = { version = "0.15", optional = true }
slack = { version = "0.25", optional = true }
[features]
default = []
irc-adapter = ["irc"]
slack-adapter = ["slack"]
Be aware that updating these dependencies is likely to break your code, since there are probably API changes in between your current and the latest version of these crates.
Just update your dependencies especially
[dependencies]
irc = { version = "0.15.0", optional = true }
slack = { version = "0.25.0", optional = true }
seem to be troublesome.

Only one of runetimes can be active error when only one runtime specified

What is going on here:
From Cargo.toml:
name = "sitegen"
version = "0.2.0"
edition = "2021"
[dependencies]
axum_database_sessions = { version = "5.0", features = [ "mysql-native"] }
sqlx = { version = "0.6", features = ["runtime-tokio-rustls", "mysql"] }
tokio = { version = "1.0", features = ["full"] }
Compile Error:

error: could not compile `sqlx-rt` due to previous error
I am using the latest rust x86-64 on linux, MySQL, and having rustls present in Cargo.toml or not makes no difference. Any suggestions? Just makes no sense to me...
Just trying to compile it to start using it with axum-sessions
The default features of axum_database_session is ["postgres-rustls"] therefore if you want to use *-native you have to disable default features:
axum_database_sessions = { version = "5.0", default-features = false, features = ["mysql-native"] }
but since you're explicitly including rustls in your dependency on sqlx you probably just want to use mysql-rustls instead, still without the default features because you're using MySQL instead of PostgreSQL:
axum_database_sessions = { version = "5.0", default-features = false, features = ["mysql-rustls"] }

rust-gpu how to use as a dependency?

I am trying to integrate rust-gpu into a project. The docs explain how to use it as a build dependency but the examples use it as a straight dependency, I have struggled with both but I would prefer to get the dependency version to work as it's more suited for my purposes.
I downloaded the rust-gpu git repo and compiled the ash example, which runs.
This is the toml I used for compilation:
[package]
name = "example-runner-ash"
version = "0.0.0"
authors = ["Embark <opensource#embark-studios.com>"]
edition = "2021"
license = "MIT OR Apache-2.0"
publish = false
# See rustc_codegen_spirv/Cargo.toml for details on these features
[features]
default = ["use-compiled-tools"]
use-installed-tools = ["spirv-builder/use-installed-tools"]
use-compiled-tools = ["spirv-builder/use-compiled-tools"]
[dependencies]
ash = "0.35"
ash-window = "0.9"
winit = "0.26"
structopt = "0.3.20"
cfg-if = "1.0.0"
shared = { path = "../../shaders/shared" }
spirv-builder = { path = "../../../crates/spirv-builder", default-features = false }
# TODO: Remove this once no longer needed, only needed to make cargo-deny happy for some reason.
# https://rustsec.org/advisories/RUSTSEC-2021-0119
nix = "0.20.2"
[target.'cfg(target_os = "macos")'.dependencies]
ash-molten = { version = "0.12.0", features = ["pre-built"] }
So I thought if I did something similar on my own code it would work:
[package]
name = "vulkan_bindings"
version = "0.1.0"
edition = "2021"
[features]
default = ["use-compiled-tools"]
use-installed-tools = ["spirv-builder/use-installed-tools"]
use-compiled-tools = ["spirv-builder/use-compiled-tools"]
[dependencies]
ash = { version = "0.37.0" }
glfw = { version = "0.45.0", features = ["vulkan"] }
gpu-allocator = "0.18.0"
ash-window = "0.9"
winit = "0.26"
structopt = "0.3.20"
cfg-if = "1.0.0"
# shared = { path = "../../shaders/shared" }
spirv-builder = { path = "rust-gpu/crates/spirv-builder", default-features = false }
paste = "1.0.8"
termcolor = "1.1.3"
But this fails with a multiplicity of errors, the first of which is:
error[E0432]: unresolved import `rustc_codegen_ssa::METADATA_FILENAME`
--> /home/makogan/.cargo/git/checkouts/rust-gpu-e0a37a82a46176e6/8052971/crates/rustc_codegen_spirv/src/link.rs:9:52
|
9 | use rustc_codegen_ssa::{CodegenResults, NativeLib, METADATA_FILENAME};
| ^^^^^^^^^^^^^^^^^ no `METADATA_FILENAME` in the root
Not that I am pointing my project to the spirv-builder crate in the rust-gpu repo I downloaded, which worked for the ash example.
I also tried just following the instructions in the docs
So I declared spirv-builder as a build-dependency (using the git link) and I made a build.rs build script and copy pasted the snippet in the docs, as described.
I get the same error about missing METADATA_FILENAME.
I do have a rust-toolchain file setup just like the docs mentioned, and I tried switching the edition field in the toml to 2018, but I consistently get the same error.
I am nto sure what to do now.

Failed to load manifest for dependency

I am trying to import some primitives into pallet in substrate but when I execute cargo check I get this error: failed to load manifest for dependency 'name of primitives'
Dex pallet: https://github.com/Kabocha-Network/cumulus/tree/v0.9.13-elio/pallets/dex
Can somebody please take a look and let me know. Thank you in advance.
if you run cargo check you get:
error: failed to load manifest for workspace member `/root/cumulus/pallets/dex`
Caused by:
failed to load manifest for dependency `acala-primitives`
Caused by:
failed to load manifest for dependency `module-evm-utiltity`
Caused by:
failed to read `/root/cumulus/primitives/modules/evm-utiltity/Cargo.toml`
Caused by:
No such file or directory (os error 2)
The problem is that /root/cumulus/primitives/modules/evm-utiltity/Cargo.toml, is not found because you haven't included this pallet locally or the pallet is misplaced and located somewhere else.
Simple solutions:
1. Locate and correct
Find where the pallet is and correctly link to it, or import the pallet to the location root/cumulus/primitives/modules/evm-utiltity/Cargo.toml so it can be found.
2. Externally linking rather than importing pallets locally.
You can link to the pallet from its external source rather than importing it locally, otherwise you will find you need to take many more dependencies and store them locally just like the /root/cumulus/primitives/modules/evm-utiltity/Cargo.toml mentioned above in the error.
What you can do instead is:
Go directly to the runtime directory, which is /root/cumulus/parachain-template/runtime/Cargo.toml and link to the external dex directly from github.com/acala-network/acala
something like this:
[dependencies.pallet-dexl]
default-features = false
git = 'https://github.com/Acala-Network/acala.git'
branch = polkadot-v0.9.13
version = '3.0.0'
or actually it is still using the older dependency version, which will be like:
pallet-dex = { git = "https://github.com/Acala-Network/acala", default-features = false, branch = "polkadot-v0.9.13" }
and more specifically for this error:
module-evm-utlity = { git = "https://github.com/Acala-Network/acala", default-features = false, branch = "polkadot-v0.9.13" }
but if you link to pallet-dex from its external source, the error should disappear and you will probably not need to link acala-primitives or module-evm-utility.
https://docs.substrate.io/how-to-guides/v3/basics/pallet-integration/
also, evm-utiltity is not spelled correctly (utility).
My fix for this error was setting the correct branch value, from .17 to .18 in my pallets cargo.toml file. For the sp-io dependency I had branch = "polkadot-v0.9.17" which didn't match the polkadot-v0.9.18 version every other dependency is on.
Original with problem on sp-io (last line)
[dependencies]
codec = { package = "parity-scale-codec", version = "3.0.0", default-features = false, features = [
"derive",
] }
scale-info = { version = "2.0.1", default-features = false, features = ["derive"] }
frame-support = { default-features = false, version = "4.0.0-dev", git = "https://github.com/paritytech/substrate.git", branch = "polkadot-v0.9.18"}
frame-system = { default-features = false, version = "4.0.0-dev", git = "https://github.com/paritytech/substrate.git", branch = "polkadot-v0.9.18" }
frame-benchmarking = { default-features = false, version = "4.0.0-dev", git = "https://github.com/paritytech/substrate.git", branch = "polkadot-v0.9.18", optional = true }
sp-io = { default-features = false, git = "https://github.com/paritytech/substrate.git", branch = "polkadot-v0.9.17" }
Fix (sp-io)
sp-io = { default-features = false, git = "https://github.com/paritytech/substrate.git", branch = "polkadot-v0.9.18" }
Now the "branch" matches with everything else and my errors are gone! Back to the Substrate Kitties tutorial I go!

Resolving imports in Rust

I'm having trouble with importing rand crate from crates.io. After adding the line rand="0.8.3" and then running command cargo build for the project, it keeps displaying the same errors:
error[E0432]: unresolved import `rand`
--> main.rs:1:5
|
1 | use rand::Rng;
| ^^^^ maybe a missing crate `rand`?
error[E0433]: failed to resolve: use of undeclared crate or module `rand`
--> main.rs:4:25
|
4 | let secret_number = rand::thread_rng().gen_range(1..=11);
| ^^^^ use of undeclared crate or module `rand`
error: aborting due to 2 previous errors
the cargo.toml file
[package]
name = "roller"
version = "0.1.0"
authors = ["User"]
edition = "2018"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
rand = "0.8.3"
Basically the simplest reproducible example is this single line of code:
use rand::Rng;
fn main(){
let secret_number = rand::thread_rng().gen_range(1..=11);
print!("{}",secret_number);
}
What's wrong with it?
Just in case:

In file Cargo.toml add lines:
[dependencies]
rand="0.3.14"
And rebuild project!
It worked with these versions:
rustc 1.53.0
cargo 1.53.0
Took answer from here https://github.com/rust-lang/rust/issues/34616
got the same error when I run it with vs code(rust-analyzer).
When you press the run button
rustic main.rs this command is called in terminal, it will cause error.
Type this in terminal,
cargo build
cargo run
It works well
If you think that you did everything right and get a strange unable to import error like this then you could try cargo clean.
That will allow you to fully re-build your binary/library after that.
