Expand description
A store of Rust crates, through which their metadata can be accessed.
Note that this trait should probably not be expanding today. All new functionality should be driven through queries instead!
If you find a method on this trait named {name}_untracked
it signifies
that it’s not tracked for dependency information throughout compilation
(it’d break incremental compilation) and should only be called pre-HIR (e.g.
during resolve)
Required methods
fn def_path_hash(&self, def: DefId) -> DefPathHash
fn crate_name(&self, cnum: CrateNum) -> Symbol
fn stable_crate_id(&self, cnum: CrateNum) -> StableCrateId
fn stable_crate_id_to_crate_num(
&self,
stable_crate_id: StableCrateId
) -> CrateNum
fn def_path_hash_to_def_id(&self, cnum: CrateNum, hash: DefPathHash) -> DefId
fn def_path_hash_to_def_id(&self, cnum: CrateNum, hash: DefPathHash) -> DefId
Fetch a DefId from a DefPathHash for a foreign crate.
