Struct Parser

pub struct Parser<'a, 'p, 'ast> { /* private fields */ }

Implementations

impl<'a, 'p, 'ast> Parser<'a, 'p, 'ast>

pub fn new( arena: &'p Arena, ast_arena: &'ast Arena, str_interner: &'a StrInterner<'p>, span_mgr: &'a mut SpanManager, tokens: Vec<Token<'p, 'ast>>, ) -> Self

Creates a new parser that operates on tokens.

arena is used to allocate interned strings and ast_arena is used to allocate most of AST nodes. This allows to free most of the AST while keeping interned strings.

tokens must not include whitespace or comments and must end with an end-of-file token.

pub fn parse_root_expr(self) -> Result<Expr<'p, 'ast>, ParseError>

Parses the tokens into an expression.
