Struct ChangeSet 

pub struct ChangeSet { /* private fields */ }

Sorted, non-overlapping, non-touching edits against a document of base_len bytes.

Implementations

impl ChangeSet

pub fn new(base_len: ByteOffset, edits: Vec<Edit>) -> Self

Sorts the edits and merges touching ones (concatenating their text) and overlapping deletions. Overlapping edits that both insert text are a caller bug.

pub fn edits(&self) -> &[Edit]

pub fn is_empty(&self) -> bool

pub fn base_len(&self) -> ByteOffset

pub fn new_len(&self) -> ByteOffset

pub fn apply(&self, doc: &mut Document)

Applies the edits to doc, which must be in the base state.

pub fn invert(&self, doc: &Document) -> ChangeSet

The change set that undoes this one. doc must be in the base state.

pub fn map_position(&self, pos: ByteOffset, bias: Bias) -> ByteOffset

Maps a position in the base state to the new state.

Positions inside a replaced range move to its start (Before) or to the end of the replacement (After). A position at the start of a non-empty replaced range stays before it and one at its end stays after it, whatever the bias; the bias only decides ties at pure insertions and positions strictly inside a replaced range.
