Trait ByteStepper 

pub trait ByteStepper {
    type Output;
    type Error;

    // Required methods
    fn step(
        &mut self,
        input: Input<'_>,
        pulse: Option<&dyn Pulse>,
    ) -> Result<Stepped<Self::Output>, Self::Error>;
    fn requested(&self) -> &[InputRequest];
}

A stage that consumes bytes through the sans-I/O dialogue.

Required Associated Types

type Output

What a productive step yields: an image decode event, a demuxed packet.

type Error

The stage’s error.

Required Methods

fn step( &mut self, input: Input<'_>, pulse: Option<&dyn Pulse>, ) -> Result<Stepped<Self::Output>, Self::Error>

Take a prefix of input and report what happened. None adds no per-call control; any control retained by the stage remains active.

fn requested(&self) -> &[InputRequest]

What the stage needs next, after a Step::Need. Never empty then.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<D: ControlledIncrementalDecode, S: DecodeRowSink> ByteStepper for ControlledStepper<'_, D, S>

type Output = ControlledEvent

type Error = StepError<<D as IncrementalDecode>::Error>
