Functions

fake_token_stream

maybe_file_to_stream

Given a source file, produces a sequence of token trees. Returns any buffered errors from parsing the token stream.

maybe_new_parser_from_source_str

Creates a new parser from a source string. Returns any buffered errors from lexing the initial token stream.

Creates a new parser, handling errors as appropriate if the file doesn’t exist. If a span is given, that is used on an error as the source of the problem.

new_parser_from_source_str

Creates a new parser from a source string.

nt_to_tokenstream

parse_crate_attrs_from_file

parse_crate_attrs_from_source_str

parse_crate_from_file

parse_crate_from_source_str

parse_in

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

parse_stream_from_source_str

source_file_to_stream

Given a source_file, produces a sequence of token trees.

stream_to_parser

Given a stream and the ParseSess, produces a parser.
