Enum StepResult

pub enum StepResult {
    Pending,
    Done,
    Timeout,
    Failed,
}

Result of a state machine step.

Each call to step() returns one of these values to indicate the current state of the operation.

Variants

Pending

Operation in progress, call step() again next iteration.

Done

Operation completed successfully. Call output() to get the result.

Timeout

Operation timed out. Call error() for details.

Failed

Operation failed. Call error() for details.

Implementations

impl StepResult

pub fn is_pending(self) -> bool

Check if operation is still in progress.

pub fn is_done(self) -> bool

Check if operation completed successfully.

pub fn is_terminal(self) -> bool

Check if operation terminated (done, timeout, or failed).

pub fn is_error(self) -> bool

Check if operation ended in error (timeout or failed).

Trait Implementations

impl Clone for StepResult

fn clone(&self) -> StepResult

Returns a copy 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.
