Fields

metadata_loader: Box<MetadataLoaderDyn>

metas: IndexVec<CrateNum, Option<Box<CrateMetadata>>>

injected_panic_runtime: Option<CrateNum>

allocator_kind: Option<AllocatorKind>

This crate needs an allocator and either provides it itself, or finds it in a dependency. If the above is true, then this field denotes the kind of the found allocator.

alloc_error_handler_kind: Option<AllocatorKind>

This crate needs an allocation error handler and either provides it itself, or finds it in a dependency. If the above is true, then this field denotes the kind of the found allocator.

has_global_allocator: bool

This crate has a #[global_allocator] item.

has_alloc_error_handler: bool

This crate has a #[alloc_error_handler] item.

stable_crate_ids: StableCrateIdMap

The interned StableCrateIds.

unused_externs: Vec<Symbol>

Unused externs of the crate

Implementations

impl CStore

pub fn ctor_untracked(&self, def: DefId) -> Option<(CtorKind, DefId)>

pub fn load_macro_untracked(&self, id: DefId, tcx: TyCtxt<'_>) -> LoadedMacro

pub fn def_span_untracked(&self, def_id: DefId, sess: &Session) -> Span

pub fn def_kind_untracked(&self, def: DefId) -> DefKind

pub fn expn_that_defined_untracked( &self, def_id: DefId, sess: &Session ) -> ExpnId

pub fn num_def_ids_untracked(&self, cnum: CrateNum) -> usize

Only public-facing way to traverse all the definitions in a non-local crate. Critically useful for this third-party project: https://github.com/hacspec/hacspec. See https://github.com/rust-lang/rust/pull/85889 for context.

Trait Implementations

impl CrateStore for CStore

fn def_key(&self, def: DefId) -> DefKey

Returns the DefKey for a given DefId. This indicates the parent DefId as well as some idea of what kind of data the DefId refers to.

fn as_any(&self) -> &dyn Any

fn untracked_as_any(&mut self) -> &mut dyn Any

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(&self, def: DefId) -> DefPath

fn def_path_hash(&self, def: DefId) -> DefPathHash

fn def_path_hash_to_def_id(&self, cnum: CrateNum, hash: DefPathHash) -> DefId

Fetch a DefId from a DefPathHash for a foreign crate.

fn expn_hash_to_expn_id( &self, sess: &Session, cnum: CrateNum, index_guess: u32, hash: ExpnHash ) -> ExpnId

fn import_source_files(&self, sess: &Session, cnum: CrateNum)

Imports all SourceFiles from the given crate into the current session. This normally happens automatically when we decode a Span from that crate’s metadata - however, the incr comp cache needs to trigger this manually when decoding a foreign Span

impl Debug for CStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
