Struct RopeBuffer 

pub struct RopeBuffer { /* private fields */ }

A mutable buffer for rope-based source code, supporting efficient edits.

Implementations

impl RopeBuffer

pub fn new(input: impl ToString) -> Self

Creates a new empty RopeBuffer.

pub fn new_with_id( input: impl ToString, source_id: impl Into<Option<SourceId>>, ) -> Self

Creates a new RopeBuffer with the specified input and source ID.

pub fn snapshot(&self) -> RopeSource

Returns a read-only snapshot of the current buffer.

pub fn apply_edits_range(&mut self, edits: &[TextEdit]) -> Range<usize>

Applies multiple text edits to the buffer and returns the affected range.

pub fn apply_edits(&mut self, edits: &[TextEdit]) -> usize

Applies multiple text edits to the buffer and returns the minimum affected offset.
