Struct Transaction 

pub struct Transaction { /* private fields */ }

A pending change: a Transform plus selection and history intent.

Implementations

impl Transaction

pub fn doc(&self) -> &Node

The (in-progress) transformed document.

pub fn transform(&mut self) -> &mut Transform

Mutable access to the underlying transform (apply steps via its helpers, e.g. tx.transform().replace(..)).

pub fn set_selection(&mut self, selection: Selection) -> &mut Self

Explicitly set the selection for the resulting state.

pub fn no_history(&mut self) -> &mut Self

Exclude this transaction from undo history.

pub fn join_history(&mut self) -> &mut Self

Merge this transaction into the previous undo group (e.g. continued typing). Grouping is caller-driven in v0.1.

pub fn doc_changed(&self) -> bool

Whether the document was changed.

pub fn set_history_intent(&mut self, intent: HistoryIntent) -> &mut Self

Tag this transaction so EditorState::apply walks the undo/redo stack instead of applying steps. Used by the History extension’s commands to dispatch through the normal Command/Dispatch pipeline.

pub fn history_intent(&self) -> Option<HistoryIntent>

The history intent on this transaction, if any.

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.
