Struct rustc::hir::def_id::LocalDefId[][src]

pub struct LocalDefId(DefIndex);
🔬 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?

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.
