Struct LossyTreeSink

pub struct LossyTreeSink<'a> { /* private fields */ }

Structure to convert events to a lossy syntax tree which does not preserve whitespace.

Implementations

impl<'a> LossyTreeSink<'a>

pub fn new(text: &'a str, tokens: &'a [Token]) -> Self

pub fn with_offset( text: &'a str, tokens: &'a [Token], token_start: usize, ) -> Self

Make a new tree sink but start the sink at a specific token, this is used for making completed markers into AST nodes for rules which need them.

Panics

Panics if the token start does not line up to a token’s start index or is out of bounds

pub fn finish(self) -> (GreenNode, Vec<ParserError>)
