Type Alias TextEditUndoer 

pub type TextEditUndoer = Undoer<(CCursorRange, String)>;

Aliased Type

pub struct TextEditUndoer {
    settings: Settings,
    undos: VecDeque<(CCursorRange, String)>,
    redos: Vec<(CCursorRange, String)>,
    flux: Option<Flux<(CCursorRange, String)>>,
}

Fields

settings: Settings

undos: VecDeque<(CCursorRange, String)>

New undoes are added to the back. Two adjacent undo points are never equal. The latest undo point may (often) be the current state.

redos: Vec<(CCursorRange, String)>

Stores redos immediately after a sequence of undos. Gets cleared every time the state changes. Does not need to be a deque, because there can only be up to undos.len() redos, which is already limited to settings.max_undos.

flux: Option<Flux<(CCursorRange, String)>>
