Struct AppliedEdit 

pub struct AppliedEdit {
    pub original_range: Range,
    pub inserted_range: Range,
    pub replaced_text: String,
    pub inserted_text: String,
    pub delta: EditDelta,
}

What an apply_edit produced. The caller uses this to log change events and to construct an inverse Edit for the undo stack.

inserted_text is the text that was placed into inserted_range. We keep it on the struct so subscribers (notably the LSP fan-in, which needs range + text per change) don’t have to re-read the buffer after every applied edit.

delta is the tree-sitter-shaped sibling: byte/position deltas the syntax worker uses to drive incremental reparse via Tree::edit + Parser::parse(_, Some(&old_tree)). Constructed from values already computed during the rope mutation – no extra rope reads. See [EditDelta] for field semantics.

Fields

original_range: Range

The range the edit targeted, in pre-edit coordinates (exactly the [Edit::range] that was applied).

inserted_range: Range

Where the inserted text now sits, in post-edit coordinates: starts at original_range.start and ends after the last inserted byte. Empty for a pure delete.

replaced_text: String

The text the edit removed from original_range (empty for a pure insert). Replacing inserted_range with this text undoes the edit.

inserted_text: String

The text the edit placed at inserted_range (empty for a pure delete).

delta: EditDelta

Byte offsets and positions of the edit in tree-sitter’s InputEdit shape. Byte offsets are absolute (from the start of the buffer) and saturate at u32::MAX.
