Struct StepResult 

pub struct StepResult<T, S: EngineSpec> {
    pub output: T,
    pub outcome: StepOutcome<S>,
}

The result of a step.

Returned by the callback passed to register_step.

Fields

output: T

The output of the step.

outcome: StepOutcome<S>

The outcome associated with the step.

This outcome is serializable.

Implementations

impl<T, S: EngineSpec> StepResult<T, S>

pub fn map<U, F>(self, op: F) -> StepResult<U, S>

where F: FnOnce(T) -> U,

Maps a StepResult<T, S> to StepResult<U, S> by applying a function to the contained output value, leaving the outcome untouched.

Trait Implementations

impl<T, S: EngineSpec> Debug for StepResult<T, S>

where T: Debug,

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

Formats the value using the given formatter.
