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 can fail differently each time. 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

```rust use retry_error::RetryError;

fn some_operation() -> anyhow::Result { unimplemented!(); // example }

fn example() -> Result<(), RetryError> { const NATTEMPTS: usize = 10; let mut err = RetryError::inattemptto("perform an example operation"); for _ in 0..NATTEMPTS { match some_operation() { Ok(val) => return Ok(()), Err(e) => err.push(e), } } // All attempts failed; return all the errors. return Err(err); } ```
