Struct Backoff 

pub struct Backoff {
    pub base_windows: u32,
    pub max_shift: u32,
}

Backoff schedule, in scheduling windows (one window per crate::Residency::step call).

Fields

base_windows: u32

Wait after the first failure.

max_shift: u32

The wait doubles per failure at most this many times.

Implementations

impl Backoff

pub const GRID_DEFAULT: Backoff

The grid scheduler’s schedule: 16 windows, doubling up to 16 << 5 = 512 (about 0.27 s to 8.5 s when a window is one 60 Hz frame).

pub const fn windows(self, failure_count: u8) -> u32

Windows to wait after failure_count consecutive failures (0 when the count is 0).

Trait Implementations

impl Clone for Backoff

fn clone(&self) -> Backoff

Returns a duplicate 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 Default for Backoff

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Backoff

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