Module rustc::hir::def_id [−] [src]

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Structs

CrateNum [
Experimental
]
DefId [
Experimental
]

A DefId identifies a particular definition, by combining a crate index and a def index.
DefIndex [
Experimental
]
LocalDefId [
Experimental
]

A LocalDefId is equivalent to a DefId with krate == LOCAL_CRATE. Since we encode this information in the type, we can ensure at compile time that no DefIds from upstream crates get thrown into the mix. There are quite a few cases where we know that only DefIds from the local crate are expected and a DefId from a different crate would signify a bug somewhere. This is when LocalDefId comes in handy.

Enums

DefIndexAddressSpace [
Experimental
]

Constants

BUILTIN_MACROS_CRATE [
Experimental
]

Virtual crate for builtin macros
CRATE_DEF_INDEX [
Experimental
]

The crate root is always assigned index 0 by the AST Map code, thanks to NodeCollector::new.
DEF_INDEX_HI_START [
Experimental
]

The start of the "high" range of DefIndexes.
INVALID_CRATE [
Experimental
]

A CrateNum value that indicates that something is wrong.
LOCAL_CRATE [
Experimental
]

Item definitions in the currently-compiled crate would have the CrateNum LOCAL_CRATE in their DefId.
RESERVED_FOR_INCR_COMP_CACHE [
Experimental
]

A special CrateNum that we use for the tcx.rcache when decoding from the incr. comp. cache.
