Struct Retry 

pub struct Retry<E = Error> { /* private fields */ }

Exponential-backoff retry helper.

Implementations

impl<E> Retry<E>

pub fn new(cfg: RetryConfig<E>) -> Self

Build a Retry with the given config.

pub async fn run<F, Fut, T>(&self, make_fut: F) -> Result<T, E>

where F: FnMut() -> Fut, Fut: Future<Output = Result<T, E>>,

Execute make_fut up to max_attempts times, backing off between tries.

make_fut is a closure (not a single future) so we can re-poll a fresh future on each attempt — most futures aren’t Clone.

Trait Implementations

impl<E: Clone> Clone for Retry<E>

fn clone(&self) -> Retry<E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E: Debug> Debug for Retry<E>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
