}

Type of buffer modification.

Describes what kind of change was made to the buffer.

Variants

Insert

Text was inserted at a position.

Fields

start: (u32, u32)

Start position (line, column) - 0-indexed

text: String

The inserted text

start_byte: usize

Byte offset where the insertion begins (for incremental parsing).

Delete

Text was deleted from a range.

Fields

start: (u32, u32)

Start position (line, column) - 0-indexed

end: (u32, u32)

End position (line, column) - 0-indexed

text: String

The deleted text

start_byte: usize

Byte offset where the deletion begins (for incremental parsing).

Replace

Text was replaced (delete + insert combined).

Fields

start: (u32, u32)

Start position (line, column) - 0-indexed

end: (u32, u32)

End position (line, column) - 0-indexed

old_text: String

Old text that was replaced

new_text: String

New text

start_byte: usize

Byte offset where the replacement begins (for incremental parsing).

FullReplace

Entire buffer content was replaced (e.g., file reload).

Trait Implementations

impl Clone for Modification

fn clone(&self) -> Modification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Modification

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

Formats the value using the given formatter.

impl PartialEq for Modification

fn eq(&self, other: &Modification) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
