Struct serde_spaniel::prompt::ReplayPrompt

pub struct ReplayPrompt<P> { /* private fields */ }

Prompt decorator which logs responses and can replay them.

This prompt is used to facilitate undo and restart operations while interactively deserialising. The deserialiser itself cannot be stepped backwards once a response has been submitted. It’s necessary to start the deserialiser again, but the ReplayPrompt can quickly bring it up to the correct point by replaying its log.

Implementations

impl<P> ReplayPrompt<P>

pub fn new(inner: P) -> Self

pub fn reset(&mut self)

Clear log and disable recording.

pub fn record(&mut self)

Start recording responses.

pub fn replay(&mut self) -> Result<()>

Replay log and continue recording new responses.

pub fn undo(&mut self, n: usize)

Remove the last n responses from the log.

pub fn restart_from(&mut self, n: usize)

Truncate the log to the first nth responses in the log.
