Crate ra_ap_base_db[−][src]

base_db defines basic database traits. The concrete DB is defined by ide.

Modules

Fixtures are strings containing rust source code with optional metadata. A fixture without metadata is parsed into a single source file. Use this to test functionality local to one file.

Structs

AnchoredPath	Path relative to a file.
AnchoredPathBuf	Path relative to a file.
Canceled	An “error” signifying that the operation was canceled.
Change	Encapsulate a bunch of raw `.set` calls on the database.
CrateData
CrateDisplayName
CrateGraph	`CrateGraph` is a bit of information which turns a set of text files into a number of Rust crates. Each crate is defined by the `FileId` of its root module, the set of cfg flags (not yet implemented) and the set of dependencies. Note that, due to cfg’s, there might be several crates for a single `FileId`! As in the rust-lang proper, a crate does not have a name. Instead, names are specified on dependency edges. That is, a crate might be known under different names in different dependent crates.

FileId	Handle to a file in `Vfs`

FilePosition
FileRange
FileSet	A set of `VfsPath`s identified by `FileId`s.

SourceRoot
SourceRootCratesQuery
SourceRootId	Files are grouped into source roots. A source root is a directory on the file systems which is watched for changes. Typically it corresponds to a Rust crate. Source roots might be nested: in this case, a file belongs to the nearest enclosing source root. Paths to files are always relative to a source root, and the analyzer does not know the root path of the source root at all. So, a file from one source root can’t refer to a file in another source root by path.

VfsPath	Path in `Vfs`.

SourceDatabase	Database which stores all significant input facts: source code and project model. Everything else in rust-analyzer is derived from these queries.
SourceDatabaseExt	We don’t want to give HIR knowledge of source roots, hence we extract these methods into a separate DB.
