Struct RetryConfigBuilder 

pub struct RetryConfigBuilder<E> { /* private fields */ }

Builder for RetryConfig.

Implementations

impl<E> RetryConfigBuilder<E>

pub fn new() -> Self

Creates a new builder with defaults.

Defaults:

• max_attempts: 3
• backoff: Exponential with 100ms initial interval
• name: "<unnamed>"

pub fn max_attempts(self, max_attempts: usize) -> Self

Sets the maximum number of retry attempts.

This includes the initial attempt, so max_attempts=3 means 1 initial attempt + 2 retries.

pub fn fixed_backoff(self, duration: Duration) -> Self

Sets a fixed backoff interval.

pub fn exponential_backoff(self, initial_interval: Duration) -> Self

Sets exponential backoff with default settings.

pub fn backoff<I>(self, interval_fn: I) -> Self

where I: IntervalFunction + 'static,

Sets a custom interval function for backoff.

pub fn retry_on<F>(self, predicate: F) -> Self

where F: Fn(&E) -> bool + Send + Sync + 'static,

Sets a predicate to determine which errors should be retried.

pub fn name<S: Into<String>>(self, name: S) -> Self

Sets the name for this retry instance (used in events).

pub fn on_retry<F>(self, f: F) -> Self

where F: Fn(usize, Duration) + Send + Sync + 'static,

Registers a callback for retry events.

pub fn on_success<F>(self, f: F) -> Self

where F: Fn(usize) + Send + Sync + 'static,

Registers a callback for success events.

pub fn on_error<F>(self, f: F) -> Self

where F: Fn(usize) + Send + Sync + 'static,

Registers a callback for error events (exhausted retries).

pub fn on_ignored_error<F>(self, f: F) -> Self

where F: Fn() + Send + Sync + 'static,

Registers a callback for ignored error events.

pub fn build(self) -> RetryConfig<E>

Builds the retry configuration.
