We don’t want to give HIR knowledge of source roots, hence we extract these methods into a separate DB.

Required Methods

fn file_source_root(&self, file_id: FileId) -> SourceRootId

Path to a file, relative to the root of its source root. Source root of the file.

fn set_file_source_root(&mut self, file_id: FileId, value__: SourceRootId)

Set the value of the file_source_root input.

See file_source_root for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.

fn set_file_source_root_with_durability( &mut self, file_id: FileId, value__: SourceRootId, durability__: Durability, )

Set the value of the file_source_root input with a specific durability instead of the default of Durability::LOW. You can use Durability::MAX to promise that its value will never change again.

See file_source_root for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.

fn source_root(&self, id: SourceRootId) -> Arc<SourceRoot>

Contents of the source root.

fn set_source_root(&mut self, id: SourceRootId, value__: Arc<SourceRoot>)

Set the value of the source_root input.

See source_root for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.

fn set_source_root_with_durability( &mut self, id: SourceRootId, value__: Arc<SourceRoot>, durability__: Durability, )

Set the value of the source_root input with a specific durability instead of the default of Durability::LOW. You can use Durability::MAX to promise that its value will never change again.

See source_root for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.

fn source_root_crates(&self, id: SourceRootId) -> Arc<[CrateId]>

Crates whose root fool is in id.
