lex_token_trees_for_span 🔒

new_parser_from_file

Creates a new parser from a filename. On failure, the errors must be consumed via unwrap_or_emit_fatal, emit, cancel, etc., otherwise a panic will occur when they are dropped.

new_parser_from_source_file 🔒

Given a session and a source_file, return a parser. Returns any buffered errors from lexing the initial token stream.

new_parser_from_source_str

Creates a new parser from a source string.

parse_in

Runs the given subparser f on the tokens of the given attr’s item.

source_file_to_stream 🔒

Given a source file, produces a sequence of token trees.

source_str_to_stream

Given a source string, produces a sequence of token trees.
