[−][src]Struct redo::record::Checkpoint

pub struct Checkpoint<'a, C: Command, F> { /* fields omitted */ }

Wraps a record and gives it checkpoint functionality.

Implementations

impl<C: Command, F: FnMut(Signal), '_> Checkpoint<'_, C, F>[src]

pub fn apply(&mut self, command: C) -> Result<C>[src]

Calls the apply method.

pub fn undo(&mut self) -> Result<C>[src]

Calls the undo method.

pub fn redo(&mut self) -> Result<C>[src]

Calls the redo method.

pub fn commit(self)[src]

Commits the changes and consumes the checkpoint.

pub fn cancel(self) -> Result<C>[src]

Cancels the changes and consumes the checkpoint.

Errors

If an error occur when canceling the changes, the error is returned and the remaining commands are not canceled.

pub fn queue(&mut self) -> Queue<'_, C, F>[src]

Returns a queue.

pub fn checkpoint(&mut self) -> Checkpoint<'_, C, F>[src]

Returns a checkpoint.

pub fn target(&self) -> &C::Target[src]

Returns a reference to the target.
