Crate rustc_parse

The main parser interface.

Modules

• errors 🔒
• 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.
• panictry_buffer 🔒
  A variant of ‘panictry!’ that works on a Vec<Diagnostic> instead of a single DiagnosticBuilder.

Constants

• CFG_ATTR_GRAMMAR_HELP 🔒
• CFG_ATTR_NOTE_REF 🔒
• MACRO_ARGUMENTS

Statics

• DEFAULT_LOCALE_RESOURCE
  Raw content of Fluent resource for this crate, generated by fluent_messages macro, imported by rustc_driver to include all crates’ resources in one bundle.

Functions

• error_malformed_cfg_attr_missing 🔒
• fake_token_stream_for_crate
• fake_token_stream_for_item
• 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 session and a source_file, 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.
• parse_cfg_attr
• 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_parser 🔒
  Given a session and a source_file, 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.
