Struct CrateGraphBuilder

pub struct CrateGraphBuilder { /* private fields */ }

Implementations

impl CrateGraphBuilder

pub fn add_crate_root( &mut self, root_file_id: FileId, edition: Edition, display_name: Option<CrateDisplayName>, version: Option<String>, cfg_options: CfgOptions, potential_cfg_options: Option<CfgOptions>, env: Env, origin: CrateOrigin, is_proc_macro: bool, proc_macro_cwd: Arc<AbsPathBuf>, ws_data: Arc<CrateWorkspaceData>, ) -> Idx<CrateBuilder>

pub fn add_dep( &mut self, from: Idx<CrateBuilder>, dep: Dependency<Idx<CrateBuilder>>, ) -> Result<(), CyclicDependenciesError>

pub fn set_in_db( self, db: &mut (dyn RootQueryDb + 'static), ) -> HashMap<Idx<CrateBuilder>, Crate, FxBuildHasher>

pub fn iter(&self) -> impl Iterator<Item = Idx<CrateBuilder>>

pub fn transitive_deps( &self, of: Idx<CrateBuilder>, ) -> impl Iterator<Item = Idx<CrateBuilder>>

Returns an iterator over all transitive dependencies of the given crate, including the crate itself.

pub fn extend( &mut self, other: CrateGraphBuilder, proc_macros: &mut HashMap<Idx<CrateBuilder>, Result<(String, AbsPathBuf), String>, FxBuildHasher>, ) -> HashMap<Idx<CrateBuilder>, Idx<CrateBuilder>, FxBuildHasher>

Extends this crate graph by adding a complete second crate graph and adjust the ids in the [ProcMacroPaths] accordingly.

This will deduplicate the crates of the graph where possible. Furthermore dependencies are sorted by crate id to make deduplication easier.

Returns a map mapping other’s IDs to the new IDs in self.

pub fn remove_crates_except( &mut self, to_keep: &[Idx<CrateBuilder>], ) -> Vec<Option<Idx<CrateBuilder>>>

Removes all crates from this crate graph except for the ones in to_keep and fixes up the dependencies. Returns a mapping from old crate ids to new crate ids.

pub fn shrink_to_fit(&mut self)
