Builder for RetryConfig.

Implementations§

source§

impl RetryConfigBuilder

source

pub fn new() -> RetryConfigBuilder

Creates a new builder.

source

pub fn set_mode( &mut self, retry_mode: Option<RetryMode> ) -> &mut RetryConfigBuilder

Sets the retry mode.

source

pub fn mode(self, mode: RetryMode) -> RetryConfigBuilder

Sets the retry mode.

source

pub fn set_max_attempts( &mut self, max_attempts: Option<u32> ) -> &mut RetryConfigBuilder

Sets the max attempts. This value must be greater than zero.

source

pub fn max_attempts(self, max_attempts: u32) -> RetryConfigBuilder

Sets the max attempts. This value must be greater than zero.

source

pub fn set_initial_backoff( &mut self, initial_backoff: Option<Duration> ) -> &mut RetryConfigBuilder

Set the initial_backoff duration. This duration should be non-zero.

source

pub fn initial_backoff(self, initial_backoff: Duration) -> RetryConfigBuilder

Set the initial_backoff duration. This duration should be non-zero.

source

pub fn take_unset_from(self, other: RetryConfigBuilder) -> RetryConfigBuilder

Merge two builders together. Values from other will only be used as a fallback for values from self Useful for merging configs from different sources together when you want to handle “precedence” per value instead of at the config level

Example
let a = RetryConfigBuilder::new().max_attempts(1);
let b = RetryConfigBuilder::new().max_attempts(5).mode(RetryMode::Adaptive);
let retry_config = a.take_unset_from(b).build();
// A's value take precedence over B's value
assert_eq!(retry_config.max_attempts(), 1);
// A never set a retry mode so B's value was used
assert_eq!(retry_config.mode(), RetryMode::Adaptive);
source

pub fn build(self) -> RetryConfig

Builds a RetryConfig.

impl PartialEq<RetryConfigBuilder> for RetryConfigBuilder

source§

fn eq(&self, other: &RetryConfigBuilder) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
