Functions

for_each_break_expr

Calls cb on each break expr inside of body that is applicable for the given label.

for_each_tail_expr

Calls cb on each expression inside expr that is at “tail position”. Does not walk into break or return expressions. Note that modifying the tree while iterating it will cause undefined iteration which might potentially results in an out of bounds panic.

get_path_at_cursor_in_tt

Parses the path the identifier is part of inside a token tree.

get_path_in_derive_attr

Parses and returns the derive path at the cursor position in the given attribute, if it is a derive. This special case is required because the derive macro is a compiler builtin that discards the input derives.

item_name

lint_eq_or_in_group

Checks if the given lint is equal or is contained by the other lint which may or may not be a group.

mod_path_to_ast

Converts the mod path struct into its ast representation.

parse_tt_as_comma_sep_paths

Parses the input token tree as comma separated plain paths.

pick_best_token

Picks the token with the highest rank returned by the passed in function.

try_resolve_derive_input

Parses and resolves the path at the cursor position in the given attribute, if it is a derive. This special case is required because the derive macro is a compiler builtin that discards the input derives.

visit_file_defs

Iterates all ModuleDefs and Impl blocks of the given file.
