I'm trying to get a simple timer set up in rust that returns true at a certain frequency.
#[derive(Clone, Debug)]
pub struct IntervalTimer {
pub period: Duration,
pub delta: Instant,
}
impl IntervalTimer {
pub fn new(period: Duration) -> Self {
let delta = Instant::now();
Self { period, delta }
}
/// Returns true if the interval between calls has exceeded the period
pub fn ready(&mut self) -> bool {
if self.delta.elapsed() < self.period {
false
} else {
self.delta = self.delta + self.period;
true
}
}
}
For some reason, this seems to consistently panic when using std::time::Instant within rayon tasks (running in Legion ECS if that matters).
This was the only other post with information in it that gives the same info but it came down to using an unusual kernel. I'm just using Ubuntu 18.04 with nothing unusual set up.
https://github.com/rust-lang/rust/issues/59673
Additionally, I've tried multiple machines but the same error occurs witht he code.
Is this something to do with using std::time::Instant and rayon?

Your code is completely correct. You should submit a bug to https://github.com/rust-lang/rust. Windows and ARM Linux already have workarounds for similar issues.
My guess is that the task is jumping around to different cores and their clocks are not in lockstep, thus causing the non-monotonicity.
elapsed() just calculates now() - *self So instead of checking elapsed() > period check if now() > delta + period

Stripping debug info in the release profile reduces my crate's binary size by a third (from 1.9 MB to 1.3 MB). This is what I added:
[profile.release]
strip = true
# or strip = "symbols"
Why is stripping disabled by default in the release profile?
I read the section on strip cargo option but I'm still a bit unsure about its internals.
Are there any cons of always using it in the release profile - perhaps only increasing compilation time?
Debug info is, well, information that is useful in debugging. In particular, certain parts of the binary are mapped to source code in a way that helps you debug a --release binary.
For example, given this code:
fn main() {
foo();
}
#[inline(never)]
fn foo() {
panic!("hello");
}
The stacktrace with debug info included looks like this (running RUST_BACKTRACE=full cargo run --release):

The recent days I've been encountering this
thread panicked while panicking. aborting.
error: test failed, to rerun pass '--lib'
Caused by:
process didn't exit successfully: `C:\Users\Windows10\Projects\Rust\current\rs-sb3\target\debug\deps\sb3-44311f04214ba6d4.exe` (exit code: 0xc0000409, STATUS_STACK_BUFFER_OVERRUN)
Some day when I open my laptop, the code will just unit test perfectly fine. But after some modification to the code then the error will appear. If I tried to comment out the suspect code then the error will still come up. After awhile I cloned the repo to my pc then it works. Some modification later, the error came up.
This is my repo. I cannot provide the exact code due to my zero understanding of the problem.
It's a bug in assert_eq_sorted.
I managed to reduce it down to the following minimal reproducible example:
#[cfg(test)]
mod test {
use pretty_assertions_sorted::assert_eq_sorted;
use serde_json::json;
#[test]
fn double_panic() {
assert_eq_sorted!(json!({"a":0}), json!(null));
}
}
When run with cargo test -- --nocapture:

thread panicked while panicking. aborting.
It seems that the pretty_assertions_sorted crate has a panic! in one of its functions, causing a double panic.
Disclaimer - personal opinion: Such an error is an indication of bad programming style, in my opinion. I'd avoid the crate for now. (time of writing: pretty_assertions_sorted 1.2.0)
Here is the full reproduction of the error:
#[cfg(test)]
mod test {
use pretty_assertions_sorted::{assert_eq_sorted, Comparison, SortedDebug};
use serde_json::json;
#[test]
fn double_panic_highlevel() {
assert_eq_sorted!(json!({"a":0}), json!(null));
}
#[test]
fn double_panic_midlevel1() {
format!(
"{}",
Comparison::new(
&SortedDebug::new(json!({"a":0})),
&SortedDebug::new(json!(null))
)
);
}
#[test]
fn double_panic_midlevel2() {
format!("{:#?}", &SortedDebug::new(json!({"a":0})));
}
#[test]
fn double_panic_lowlevel1() {
darrentsung_debug_parser::parse(&format!("{:?}", json!({"a":0}))).unwrap();
}
#[test]
fn double_panic_lowlevel2() {
darrentsung_debug_parser::parse("Object {\"a\": Number(0)}").unwrap();
}
}
I'm trying to implement a decision tree using rust smartcore lib.

use csv::ReaderBuilder;
use ndarray::Array2;
use ndarray_csv::Array2Reader;
fn main() {
let mut reader = ReaderBuilder::new()
.has_headers(true)
.delimiter(b';')
.from_path("./src/result.csv")
.expect("can create reader");
let array: Array2<f64> = reader
.deserialize_array2_dynamic()
.expect("can deserialize array");
let data_set = DenseMatrix::from_array(
array.shape()[0],
array.shape()[1],
&array.as_slice().unwrap()
);
let data = data_set.slice( 0..data_set.shape().0 , 0..3);
let targets = data_set.slice( 0..data_set.shape().0 , 3..6);
let tree = DecisionTreeClassifier::fit(&data, &targets.to_row_vector(), Default::default()).unwrap();
let _y_hat = tree.predict(&data).unwrap(); // use the same data for prediction
}

I have 235201 line in the csv file. I don't have any empty line and even if I change the number of rows the error changes accordingly. How can I fix this error?
I have a Rust web on a remote server which I run as:
RUST_BACKTRACE=1 nohup /home/my_user/app123 &
When it goes down and I check nohup.log, I see only this:
04:52:22 [WARN] unexpected chunk when body cannot write
04:52:23 [WARN] unexpected chunk when body cannot write

How can I trace the error? It's something related to Serde JSON, but what exactly? There are many places in my app where it could occur.
There aren't any line numbers in your stack backtrace so the binary running on your server must have been built without debug symbols. As described in How to get a release build with debugging information when using cargo?, add the following section to Cargo.toml of your main binary:
[profile.release]
debug = true
This will include filename and line number information in the binary that can be printed when a panic occurs, making your stack backtraces more useful in the future.
ErrorImpl { code: EofWhileParsingValue, line: 1, column: 0 }
For now, the best we can tell without a backtrace is that you tried to parse an empty JSON string. For example the following triggers the same error.
extern crate serde_json;
fn main() {
let _: u64 = serde_json::from_str("").unwrap();
}
As a reminder, Result::unwrap() is not an appropriate way to handle errors in a production application. ;-)
I'm having trouble getting my VIM to correctly syntax highlight php short tags.
let php_sql_query=1
let php_htmlInStrings=1
let php_noShortTags=0
let php_folding=0
let php_baselib=1
let php_asp_tags=0
let php_parent_error_close=1
let php_parent_error_open=1
"let php_sync_method=10 " Sync only 10 lines backwards
let php_alt_comparisons=1
let php_alt_assignByReference=1
Is all all set in my vimrc file already. I can't find any help on noShortTags but changing from 0 to 1 has no effect.

I was hoping php (line 22) would take care of it. I have taken a screen shot (below) which shows how it is highlighted with long tags (line 60) and with short tags (line 61, 62, 89-92).
Screenshot
A user over on reddit found that VIM's php sytntax only checks that php_noShortTags exists. Simply commenting it out or removing from my .vimrc file fixed it.
