Enum Readiness 

#[non_exhaustive]
pub enum Readiness {
    NotReady,
    ReadyUnderPressure,
    Ready,
}

Readiness level derived from inputs and backpressure state.

Contract followed by runtimes:

• NotReady: all inputs empty (no work).
• ReadyUnderPressure: some input available AND at least one output watermark is BetweenSoftAndHard or AtOrAboveHard.
• Ready: some input available AND all outputs are BelowSoft.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotReady

No input available or blocked by backpressure.

ReadyUnderPressure

Input(s) available but under pressure.

Ready

Input(s) available and not under pressure.

Trait Implementations

impl Clone for Readiness

fn clone(&self) -> Readiness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Readiness

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

Formats the value using the given formatter.

impl PartialEq for Readiness

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

impl Copy for Readiness
