Structs

CrateId
DefId

A DefId identifies a particular definition, by combining a crate index and a def index.

DefIndex

A DefIndex is an index into the hir-map for a crate, identifying a particular definition. It should really be considered an interned shorthand for a particular DefPath.

LocalDefId

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

CrateNum

Constants

CRATE_DEF_INDEX

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

LOCAL_CRATE

Item definitions in the currently-compiled crate would have the CrateNum LOCAL_CRATE in their DefId.
