Functions

binary_lit
byte_lit	Parse a string representing a byte literal into its final form. Similar to char_lit
char_lit	Parse a string representing a character literal into its final form. Rather than just accepting/rejecting a given literal, unescapes it as well. Can take any slice prefixed by a character escape. Returns the character and the number of characters consumed.
file_to_filemap	Given a session and a path and an optional span (for error reporting), add the path to the session's codemap and return the new filemap.
filemap_to_parser	Given a filemap and config, return a parser
filemap_to_tts	Given a filemap, produce a sequence of token-trees
float_lit
integer_lit
maybe_aborted	Abort if necessary
new_parse_sess
new_parse_sess_special_handler
new_parser_from_file	Create a new parser, handling errors as appropriate if the file doesn't exist
new_parser_from_source_str
new_parser_from_tts
new_sub_parser_from_file	Given a session, a crate config, a path, and a span, add the file at the given path to the codemap, and return a parser. On an error, use the given span as the source of the problem.
parse_crate_attrs_from_file
parse_crate_attrs_from_source_str
parse_crate_from_file
parse_crate_from_source_str
parse_expr_from_source_str
parse_item_from_source_str
parse_meta_from_source_str
parse_stmt_from_source_str
parse_tts_from_source_str
raw_str_lit	Parse a string representing a raw string literal into its final form. The only operation this does is convert embedded CRLF into a single LF.
str_lit	Parse a string representing a string literal into its final form. Does unescaping.
string_to_filemap	Given a session and a string, add the string to the session's codemap and return the new filemap
tts_to_parser	Given tts and cfg, produce a parser
