Module ra_ap_ide_db::helpers

A module with ide helpers for high-level ide features.

Modules

generated_lints

Generated by sourcegen_lint_completions, do not edit by hand.

import_assets

Look up accessible paths for items.

insert_use

Handle syntactic aspects of inserting a new use.

merge_imports

Handle syntactic aspects of merging UseTrees.

rust_doc

Structs

FamousDefs

Helps with finding well-know things inside the standard library. This is somewhat similar to the known paths infra inside hir, but it different; We want to make sure that IDE specific paths don’t become interesting inside the compiler itself as well.

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.

item_name

mod_path_to_ast

Converts the mod path struct into its ast representation.

pick_best_token

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

try_resolve_derive_input_at

Resolves the path at the cursor token as a derive macro if it inside a token tree of a derive attribute.

visit_file_defs

Iterates all ModuleDefs and Impl blocks of the given file.
