Crate retry_error[−][src]
Expand description
An error attempt to represent multiple failures.
This crate implements RetryError
, a type to use when you
retry something a few times, and all those attempts. Instead of
returning only a single error, it records all of the errors
received, in case they are different.
This crate is developed as part of Arti, a project to implement Tor in Rust. It’s used by higher-level crates that retry operations.
Example
use retry_error::RetryError;
const N_ATTEMPTS: usize = 10;
let mut err = RetryError::in_attempt_to("perform an example operation");
for _ in 0..N_ATTEMPTS {
match some_operation() {
Ok(val) => return Ok(val),
Err(e) => err.push(e),
}
}
// All attempts failed; return all the errors.
return Err(err)
Structs
