pub struct Data { /* private fields */ }

Implementations

impl Data

pub fn new(bytes: Vec<u8>, history_limit: usize) -> Self

pub fn get(&self, i: usize) -> Option<u8>

pub fn set(&mut self, i: usize, byte: u8) -> Result<(), Error>

pub fn bytes(&self) -> &[u8]

pub fn dirty(&self) -> bool

pub fn reset_dirty(&mut self)

pub fn push_change(&mut self, offset: usize, new: Vec<u8>) -> usize

Pushes a change to the history and updates the data. Returns the number of bytes changed. Panics if the offset is out of bounds.

pub fn undo(&mut self) -> Option<&Change>

Undo the last change. Returns the change that was undone, if any.

pub fn redo(&mut self) -> Option<&Change>

Redo the last change. Returns the change that was redone, if any.

pub fn clear_history(&mut self)

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Data

fn fmt(&self, f: &mut Formatter<'_>) -> Result
