Crate undo [] [src]

An undo/redo library with dynamic dispatch and automatic command merging. It uses the Command Pattern where the user modifies a receiver by applying Commands on it.

The library has currently two data structures that can be used to modify the receiver:

  • A simple Stack that pushes and pops commands to modify the receiver.
  • A Record that can roll the state of the receiver forwards and backwards.
