Crate rustc_parse

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

The main parser interface.

Modules

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

Macros

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

Functions

file_to_source_file	Internal 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	Internal Given a source file, produces a sequence of token trees. Returns any buffered errors from parsing the token stream.
maybe_new_parser_from_file	Internal 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	Internal Creates a new parser from a source string. Returns any buffered errors from lexing the initial token stream.
maybe_source_file_to_parser	Internal Given a source_file and config, return a parser. Returns any buffered errors from lexing the initial token stream.
new_parser_from_file	Internal 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	Internal Creates a new parser from a source string.
new_parser_from_tts	Internal
nt_to_tokenstream	Internal
parse_crate_attrs_from_file	Internal
parse_crate_attrs_from_source_str	Internal
parse_crate_from_file	Internal
parse_crate_from_source_str	Internal
parse_in	Internal Runs the given subparser f on the tokens of the given attr's item.
parse_stream_from_source_str	Internal
prepend_attrs	Internal
source_file_to_parser	Internal Given a source_file and config, returns a parser.
source_file_to_stream	Internal Given a source_file, produces a sequence of token trees.
stream_to_parser	Internal Given a stream and the ParseSess, produces a parser.
try_file_to_source_file	Internal 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.
