Struct tikv_client::backoff::Backoff

pub struct Backoff { /* private fields */ }

When a request is retried, we can backoff for some time to avoid saturating the network.

Backoff is an object which determines how long to wait for.

Implementations

impl Backoff

pub fn next_delay_duration(&mut self) -> Option<Duration>

pub fn is_none(&self) -> bool

True if we should not backoff at all (usually indicates that we should not retry a request).

pub fn current_attempts(&self) -> u32

Returns the number of attempts

pub const fn no_backoff() -> Backoff

Don’t wait. Usually indicates that we should not retry a request.

pub const fn no_jitter_backoff( base_delay_ms: u64, max_delay_ms: u64, max_attempts: u32 ) -> Backoff

pub fn full_jitter_backoff( base_delay_ms: u64, max_delay_ms: u64, max_attempts: u32 ) -> Backoff

pub fn equal_jitter_backoff( base_delay_ms: u64, max_delay_ms: u64, max_attempts: u32 ) -> Backoff

pub fn decorrelated_jitter_backoff( base_delay_ms: u64, max_delay_ms: u64, max_attempts: u32 ) -> Backoff

Trait Implementations

impl Clone for Backoff

fn clone(&self) -> Backoff

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Backoff

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

Formats the value using the given formatter.

impl PartialEq for Backoff

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