Struct rustc_span::def_id::LocalDefId
source · pub struct LocalDefId {
pub local_def_index: DefIndex,
}
Expand description
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 DefId
s from upstream crates get thrown into the mix. There are quite a
few cases where we know that only DefId
s from the local crate are expected;
a DefId
from a different crate would signify a bug somewhere. This
is when LocalDefId
comes in handy.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
