Struct rslint_parser::LosslessTreeSink

pub struct LosslessTreeSink<'a> { /* fields omitted */ }

Structure for converting events to a syntax tree representation, while preserving whitespace.

LosslessTreeSink also handles attachment of trivia (whitespace) to nodes.

Implementations

impl<'a> LosslessTreeSink<'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>)
