Module retry 

A retry strategy that works with rusts native std::error::Error type.

TODO: Could make the impl of RetryableError trait into a proc-macro to auto-derive Retryable on annotated enum variants.

#[derive(Debug, Error)]
enum ErrorFoo {
    #[error("I am retryable")]
    #[retryable]
    Retryable,
    #[error("Nested errors are retryable")]
    #[retryable(inherit)]
    NestedRetryable(AnotherErrorWithRetryableVariants),
    #[error("Always fail")]
    NotRetryable
}

Traits

RetryableError

Specifies which errors are retryable. All Errors are not retryable by-default.

Functions

arc_retryable_to_error

Convert an Arc<[RetryableError]> to a Standard Library Arc<Error>

with_retry_deadline

Run future so that every rate-limit wait of [retry_async!] inside it ends by deadline. A wait that would pass it returns the rejection at once, so a caller that times out at deadline still sees the delay. A nested scope keeps the earlier deadline.
