Unlike the rest of the crates, these don't have a "tor-" or "arti-" prefix, and are potentially used by code outside arti. With that in mind, it's probably for the best not to bump them to 0.2.0 along with the rest of our crates. They have had no changes since 0.1.0 other than refactoring and changing of clippy lints. Therefore, I'm not bumping the dependencies from other crates onto these: it's fine whether our other crates use caret/retry-error 0.1.0 or 0.1.1. |

retry-error
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;
fn some_operation() -> anyhow::Result<bool> {
unimplemented!(); // example
}
fn example() -> Result<(), RetryError<anyhow::Error>> {
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(()),
Err(e) => err.push(e),
}
}
// All attempts failed; return all the errors.
return Err(err);
}
