The main parser interface.

Modules

lexer
parser
validate_attr	Meta-syntax validation logic of attributes for post-expansion.

Macros

maybe_recover_from_interpolated_ty_qpath	If the next tokens are ill-formed $ty:: recover them as <$ty>::.
maybe_whole	Like maybe_whole_expr, but for things other than expressions.

Constants

MACRO_ARGUMENTS

Functions

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_file	Creates a new parser, returning buffered diagnostics if the file doesn't exist, or from lexing the initial 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 as the source of the problem.
new_parser_from_source_str	Creates a new parser from a source string.
