Crate ra_ap_ide_db[−][src]

Expand description

This crate defines the core datastructure representing IDE state – RootDatabase.

It is mainly a HirDatabase for semantic analysis, plus a SymbolsDatabase, for fuzzy search.

This module defines the Assist data structure. The actual assist live in the ide_assists downstream crate. We want to define the data structures in this low-level crate though, because ide_diagnostics also need them (fixits for diagnostics and assists are the same thing under the hood). We want to compile ide_assists and ide_diagnostics in parallel though, so we pull the common definitions upstream, to this crate.

call_info

This crate provides primitives for tracking the information about a call site.

defs

NameDefinition keeps information about the element we want to search references for. The element is represented by NameKind. It’s located inside some container and has a visibility, which defines a search scope. Note that the reference search is possible for not all of the classified items.

helpers

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

items_locator

This module has the functionality to search the project and its dependencies for a certain item, by its name and a few criteria. The main reason for this module to exist is the fact that project’s items and dependencies’ items are located in different caches, with different APIs.

label

See Label

line_index

LineIndex maps flat TextSize offsets into (Line, Column) representation.

path_transform

See PathTransform.

rename

Rename infrastructure for rust-analyzer. It is used primarily for the literal “rename” in the ide (look for tests there), but it is also available as a general-purpose service. For example, it is used by the fix for the “incorrect case” diagnostic.

search

Implementation of find-usages functionality.

source_change

This modules defines type to represent changes to the source code, that flow from the server to the client.

symbol_index

This module handles fuzzy-searching of functions, structs and other symbols by name across the whole workspace and dependencies.

traits

Functionality for obtaining data related to traits from the DB.

ty_filter

This module contains structures for filtering the expected types. Use case for structures in this module is, for example, situation when you need to process only certain Enums.
