Enum StepResult 

#[non_exhaustive]
pub enum StepResult {
    MadeProgress,
    NoInput,
    Backpressured,
    WaitingOnExternal,
    YieldUntil(Ticks),
    Terminal,
}

Result of a step call indicating progress and scheduling hints.

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.

MadeProgress

Work was performed (messages consumed and/or produced).

NoInput

No inputs were available to make progress.

Backpressured

Backpressure prevented progress.

WaitingOnExternal

Waiting on external completion (device, transport).

YieldUntil(Ticks)

Yield until provided tick (cooperative scheduling hint).

Terminal

Node has completed and will not produce further outputs.

Trait Implementations

impl Clone for StepResult

fn clone(&self) -> StepResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StepResult

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

Formats the value using the given formatter.

impl PartialEq for StepResult

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