Module retry 

Shared retry/backoff helpers built on top of the backon crate.

These constructors give the node a single definition of the “standard” backoff schedules so that retry behaviour stays consistent across components instead of being re-derived at each call site. Use them together with the Retryable suffix extension, e.g.

use miden_node_utils::retry::{self, Retryable};
use miden_node_tracing::warn;

let value = (|| async { do_thing().await })
    .retry(retry::exponential(min, max))
    .when(|err| is_transient(err))
    .notify(|err, dur| {
        warn!(
            err,
            "retrying",
            retry.delay_ms = dur.as_millis() as u64
        );
    })
    .await?;

Traits

BackoffBuilder

BackoffBuilder is utilized to construct a new backoff.

Retryable

Retryable will add retry support for functions that produce futures with results.

RetryableWithContext

RetryableWithContext adds retry support for functions that produce futures with results and context.

Functions

constant

Builds a constant-delay backoff schedule.

exponential

Builds an exponential backoff schedule that retries indefinitely.

exponential_bounded

Same as exponential, but stops after max_times retries (i.e. max_times + 1 total attempts).
