Struct rustc_span::def_id::DefId
source · #[repr(C)]pub struct DefId {
pub index: DefIndex,
pub krate: CrateNum,
}
Expand description
A DefId
identifies a particular definition, by combining a crate
index and a def index.
You can create a DefId
from a LocalDefId
using local_def_id.to_def_id()
.

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.
