Implementations

impl TreeBuilder

pub fn new() -> TreeBuilder

pub fn with_capacity(elements: usize, text_len: usize) -> TreeBuilder

Room for elements elements over text_len bytes of text, so the arrays never regrow.

pub fn start_node(&mut self, kind: SyntaxKind)

pub fn token(&mut self, kind: SyntaxKind, text: &str)

pub fn finish_node(&mut self)

pub fn len(&self) -> ElementId

Elements pushed so far; the id the next element gets.

pub fn is_empty(&self) -> bool

pub fn extract(&self, root: ElementId) -> Tree

A standalone copy of the finished subtree rooted at root (a node pushed at the current nesting level, with nothing pushed after its end).

pub fn push_tree(&mut self, tree: &Tree)

Appends all of tree as the next child of the open node: Self::push_subtree of its root, as block copies.

pub fn push_subtree(&mut self, tree: &Tree, e: ElementId)

Appends a copy of e’s subtree from another tree.

pub fn finish(self) -> Tree
