Constants

MACRO_ARGUMENTS

Functions

fake_token_stream
file_to_source_file	Given a session and a path and an optional span (for error reporting), adds the path to the session’s source_map and returns the new source_file.
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.
maybe_source_file_to_parser	Given a source_file and config, return a parser. Returns any buffered errors from lexing the initial token stream.
new_parser_from_file	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
prepend_attrs
source_file_to_parser	Given a source_file and config, returns a parser.
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.
try_file_to_source_file	Given a session and a path and an optional span (for error reporting), add the path to the session’s source_map and return the new source_file or error when a file can’t be read.
