Struct kernel::retry::ExpBackoff

pub struct ExpBackoff {
    min: Duration,
    max: Duration,
    cur: Duration,
}

An exponential backoff.

Fields

min: Duration

max: Duration

cur: Duration

Implementations

impl ExpBackoff

pub const DEFAULT_MAX_BACKOFF: Duration = _

The default maximum retry backoff.

pub const DEFAULT_MIN_BACKOFF: Duration = _

pub const fn new(min: Duration) -> Self

pub const fn with_max_backoff(self, max: Duration) -> Self

Sets the maximum duration to back off for.

Once the backoff duration reaches the maximum, it will no longer increase until the backoff is reset.

pub fn backoff(&mut self) -> Duration

Returns the current backoff, incrementing the backoff returned by the next call to backoff.

pub async fn wait(&mut self)

pub fn reset(&mut self)

Reset the backoff to the min value.

pub fn current(&self) -> Duration

Trait Implementations

impl Backoff for ExpBackoff

fn backoff(&mut self) -> Duration

fn reset(&mut self)

impl Clone for ExpBackoff

fn clone(&self) -> ExpBackoff

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExpBackoff

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

Formats the value using the given formatter.

impl Default for ExpBackoff

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ExpBackoff

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

Tests for self and other values to be equal, and is used by ==.

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

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