Struct BackpressurePolicy 

pub struct BackpressurePolicy {
    pub soft_limit: usize,
    pub hard_limit: usize,
}

Watermark policy for explicit backpressure.

Fields

soft_limit: usize

Soft watermark.

hard_limit: usize

Hard watermark.

Implementations

impl BackpressurePolicy

pub fn try_new(soft_limit: usize, hard_limit: usize) -> DistributeResult<Self>

Creates a validated policy.

pub fn evaluate(self, depth: usize) -> BackpressureSignal

Evaluates queue depth against watermarks.

Trait Implementations

impl Clone for BackpressurePolicy

fn clone(&self) -> BackpressurePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackpressurePolicy

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

Formats the value using the given formatter.

impl Hash for BackpressurePolicy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BackpressurePolicy

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