[−][src]Struct byte_mutator::undo_buffer::UndoBuffer
Fixed size buffer with an original state and a writeable buffer. Tracks which region of the buffer has been exposed for changes and enables an undo of those changes.
Methods
impl UndoBuffer
[src]
pub fn new(buf: &[u8]) -> Self
[src]
pub fn len(&self) -> usize
[src]
Used length of the writable buffer
pub fn is_empty(&self) -> bool
[src]
Whether the writable buffer is empty
pub fn get_mut(&mut self) -> &mut [u8]
[src]
Returns a full mutable slice of the write buffer, and marks the entire thing as dirty.
pub fn get_mut_range(&mut self, start: usize, end: usize) -> &mut [u8]
[src]
Returns a mutable subslice of the buffer. Marks that region as dirty for future undo operations.
pub fn read(&self) -> &[u8]
[src]
Returns an immutable reference to the buffer in its current state
pub fn undo(&mut self)
[src]
Undo all changes and set the write/readable buffer back to the original state
