rust how to find servcie name and port. with winsock - rust

I have one question.
I was using this.
SERVENT structure (winsock.h)
But, I can't find anything similar.
Let me know how to find service name and port number.

Your question is somewhat lacking but this might be of interest:
https://microsoft.github.io/windows-docs-rs/doc/windows/Win32/Networking/WinSock/fn.getservbyname.html
https://microsoft.github.io/windows-docs-rs/doc/windows/Win32/Networking/WinSock/fn.getservbyport.html
https://github.com/microsoft/windows-rs
https://crates.io/crates/windows
TL;DR:
cargo add windows and add Win32_Networking_WinSock as a feature to cargo.toml

Can I rename lib.rs to the crate name?

Right now I'm working on a project with multiple separate crates.
I would prefer lib.rs to be renamed to the crate's name itself, as when I open multiple at the same time it takes me an extra second to find the one I'm looking for, not a big deal just curious if it's possible or a good idea.
ne_log/lib.rs into: ne_log/ne_log.rs
Yes, in each Cargo.toml add a lib section with the desired path:
[lib]
path = "src/some_other_file.rs"
Read more here: Cargo Targets
As to whether its a good idea or not; it will make your file structure non-standard, but the option is available since there are plenty of non-standard workflows. Use your own discretion.

How to choose a specific msvcr.dl in Nim?

I would like to use an old msvcr71.dll when compiling Nim.
Is there a way to do so? If yes, how?
This is explained in the manual, right here. As StackOverflow doesn't like link responses, a copy-paste:
proc imported_proc(): ReturnType
{.cdecl, dynlib: "msvcr71.dll", importc.}
This asumes there is a function in msvcf71.dll called imported_proc that you want to wrap in your Nim code without changing the name.
You can also tweak which libraries to load when compiling, as explained here:
$ nim c --dynlibOverride:msvcr71 --passL:msvcr71.dll program.nim
Didn't test any of the code, hope it helps. You can always try to find some code that does this kind of linking, for example https://github.com/khchen/wNim/blob/master/wNim/private/winimx.nim or maybe https://github.com/brentp/hts-nim/blob/master/src/hts/private/hts_concat.nim

How can I view the source code for the readline module in nodejs?

I've scored the internet for almost an hour, but I can't find the actual github for readline, nor is it in node_modules. I hear that some are in binary, like events.js, but I found a repo for it. I'm trying to read through readline and learn how it works but I cannot find it. Does anyone know where it is?
You can find it in the libs-directory on the official github-repo:
https://github.com/nodejs/node/blob/master/lib/readline.js

List all folders named `test` in Rust using `fd-find` crate?

I want to list all folders named test when I run my Rust application as a binary.
I want to use fd-find → https://crates.io/crates/fd-find
The basic documentation shows how to call it in the terminal but doesn't tell how to call it from a rust file called main.rs.
I am new to Rust so don't know much. Any help appreciated :)
By the look of it fd-find is not shipped as a library so I guess your best bet would be something like std::process::Command.

Give an example of: groovyc --sourcepath

I am unable to get the --sourcepath option of groovyc to work at all. Can someone furnish a trivial example of it actually doing anything?
Ultimately I want to use "groovyc" at the command line with a directory a packaged organized tree of mixed groovy and java source. I don't want to reference each source file explicitly. And I don't want to use an ant or maven task either, on grounds of both principle (hey is there a bug here?) and because the production scenario that I might want to tweak the source in has neither but will have groovy. I know I could use unix find but must I resort to that?!
sourcepath isn't used anymore. It's only there for backwards compatibility and will be removed in the future.
The Groovy documentation is currently rewritten, you can find a snapshot including the documentation for groovyc here: https://dl.dropboxusercontent.com/u/20288797/groovy-documentation/index.html#ThegroovycAntTask-groovyc
