Trait BufferEdit 

pub trait BufferEdit: Send {
    // Required methods
    fn insert_at(&mut self, pos: Pos, text: &str);
    fn delete_range(&mut self, range: Range<Pos>);
    fn replace_range(&mut self, range: Range<Pos>, replacement: &str);

    // Provided method
    fn replace_all(&mut self, text: &str) { ... }
}

Mutating sub-trait of Buffer. Distinct trait name from the crate-root Edit struct — this one carries methods, the other is a value type.

Required Methods

fn insert_at(&mut self, pos: Pos, text: &str)

Insert text at pos. Implementations clamp out-of-range positions to the document end.

fn delete_range(&mut self, range: Range<Pos>)

Delete the half-open range.

fn replace_range(&mut self, range: Range<Pos>, replacement: &str)

Replace the half-open range with replacement.

Provided Methods

fn replace_all(&mut self, text: &str)

Replace the entire buffer content with text. The cursor is clamped to the surviving content. Used by :e! / undo restore / snapshot replay where expressing “replace whole buffer” via [replace_range] would require knowing the end position. Default impl uses [replace_range] with a best-effort end (u32::MAX / u32::MAX); the canonical in-tree impl overrides it for a single-shot rebuild.
