dmexe / failsafe-rs Goto Github PK

Hey,

This is commit: d8c6b73#diff-e6580009c99953c9f2fe050c1acef12a is in my opinion sufficent to bump the version number

This will solve some resolution panics that I have received thanks

Have you considered expanding this library to add other distributed reliability tools, like BulkHeads, RateLimiters, and Retry(s)? It would probably require a serious re-org to move all the stuff in the base module into a more reasonable place, but it also would be nice to have a Rust alternative to r4j or Hystrix.

Edit: I'd be willing to help, but I don't want to sink any time into it if you're not interested in taking the library in that direction and/or supporting it.

Thank you very much for this crate!
I have one question, could you please add an example how the circuit breaker is shared via multiple functions... eg

use failsafe::{CircuitBreaker, Config, Error};
use rand::{thread_rng, Rng};

fn dangerous_call() -> Result<(), ()> {
    if thread_rng().gen_range(0, 2) == 0 {
        return Err(());
    }
    Ok(())
}

fn caller(circuit_breaker: XXXX) {
    for n in 0..100 {
        match circuit_breaker.call(|| dangerous_call()) {
            Err(Error::Inner(_)) => {
                eprintln!("{}: fail", n);
            }
            Err(Error::Rejected) => {
                eprintln!("{}: rejected", n);
                break;
            }
            _ => {}
        }
    }
}

fn main() {
    caller(Config::new().build());
}

I have no clue what the type XXXX would be. Maybe others have the same issue.
Thanks a lot.
