Struct bonsaidb::keystorage::s3::aws_sdk_s3::config::retry::RetryConfig

pub struct RetryConfig { /* private fields */ }

Retry configuration for requests.

Implementations

impl RetryConfig

pub fn standard() -> RetryConfig

Creates a default RetryConfig with RetryMode::Standard and max attempts of three.

pub fn adaptive() -> RetryConfig

Creates a default RetryConfig with RetryMode::Adaptive and max attempts of three.

pub fn disabled() -> RetryConfig

Creates a RetryConfig that has retries disabled.

pub fn with_retry_mode(self, retry_mode: RetryMode) -> RetryConfig

Set this config’s retry mode.

pub fn with_max_attempts(self, max_attempts: u32) -> RetryConfig

Set the maximum number of times a request should be tried, including the initial attempt. This value must be greater than zero.

pub fn with_reconnect_mode(self, reconnect_mode: ReconnectMode) -> RetryConfig

Set the ReconnectMode for the retry strategy

By default, when a transient error is encountered, the connection in use will be poisoned. This prevents reusing a connection to a potentially bad host but may increase the load on the server.

This behavior can be disabled by setting ReconnectMode::ReuseAllConnections instead.

pub fn with_initial_backoff(self, initial_backoff: Duration) -> RetryConfig

Set the multiplier used when calculating backoff times as part of an exponential backoff with jitter strategy. Most services should work fine with the default duration of 1 second, but if you find that your requests are taking too long due to excessive retry backoff, try lowering this value.

Example

For a request that gets retried 3 times, when initial_backoff is 1 seconds:

• the first retry will occur after 0 to 1 seconds
• the second retry will occur after 0 to 2 seconds
• the third retry will occur after 0 to 4 seconds

For a request that gets retried 3 times, when initial_backoff is 30 milliseconds:

• the first retry will occur after 0 to 30 milliseconds
• the second retry will occur after 0 to 60 milliseconds
• the third retry will occur after 0 to 120 milliseconds

pub fn mode(&self) -> RetryMode

Returns the retry mode.

pub fn reconnect_mode(&self) -> ReconnectMode

Returns the ReconnectMode

pub fn max_attempts(&self) -> u32

Returns the max attempts.

pub fn initial_backoff(&self) -> Duration

Returns the backoff multiplier duration.

pub fn max_backoff(&self) -> Duration

Returns the max backoff duration.

pub fn has_retry(&self) -> bool

Returns true if retry is enabled with this config

pub fn use_static_exponential_base(&self) -> bool

Returns true if retry strategies should use a static exponential base instead of the default random base.

To set this value, the test-util feature must be enabled.

Trait Implementations

impl Clone for RetryConfig

fn clone(&self) -> RetryConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RetryConfig

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

Formats the value using the given formatter.

impl PartialEq<RetryConfig> for RetryConfig

fn eq(&self, other: &RetryConfig) -> 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.

impl Storable for RetryConfig

type Storer = StoreReplace<RetryConfig>

Specify how an item is stored in the config bag, e.g. [StoreReplace] and [StoreAppend]
