Implementations

impl<'a, L: Language> TreeSink<'a, L>

pub fn new(arena: &'a SyntaxArena, capacity_hint: usize) -> Self

Creates a new tree sink.

pub fn push_leaf(&mut self, kind: L::TokenType, len: usize)

Pushes a leaf node (token) to the current list of children.

pub fn push_node(&mut self, node: &'a GreenNode<'a, L>)

Pushes an existing node to the current list of children.

pub fn checkpoint(&self) -> usize

Returns the current number of children, serving as a checkpoint for finishing a node later.

pub fn finish_node( &mut self, checkpoint: usize, kind: L::ElementType, ) -> &'a GreenNode<'a, L>

Finishes a node starting from the given checkpoint and adds it as a child.
