Trait RetryInterceptor 

pub trait RetryInterceptor:
    Send
    + Sync
    + 'static {
    // Required method
    fn intercept(&self, event: RetryEvent<'_>);
}

RetryInterceptor is used to intercept while retry happened.

Required Methods

fn intercept(&self, event: RetryEvent<'_>)

Everytime RetryLayer is retrying, this function will be called.

Timing

just before the retry sleep.

Notes

The intercept must be quick and non-blocking. No heavy IO is allowed. Otherwise, the retry will be blocked.
