Expand description

Modify a tree-sitter parse tree when printing.

Required Methods§

Source

fn has_edit(&self, tree: &Tree, node: &Node<'_>) -> bool

Does this editor have an edit for this node?

Source

fn edit(&self, source: &[u8], tree: &Tree, node: &Node<'_>) -> Vec<u8> ⓘ

Edit this node (precondition: Editor::has_edit).

Provided Methods§

Source

fn in_order_edits<'a>( &'a self, source: &'a [u8], tree: &'a Tree, ) -> Box<dyn Iterator<Item = Edit> + 'a>

Get all edits to this tree, in order.

Edits must be ordered by start byte and must not overlap.

[default_in_order] does an in-order traversal of the tree.
