pub(crate) struct Typedef {
pub(crate) type_: Type,
pub(crate) generics: Generics,
pub(crate) item_type: Option<Type>,
}
Fields
type_: Type
generics: Generics
item_type: Option<Type>
type_
can come from either the HIR or from metadata. If it comes from HIR, it may be a type
alias instead of the final type. This will always have the final type, regardless of whether
type_
came from HIR or from metadata.
If item_type.is_none()
, type_
is guaranteed to come from metadata (and therefore hold the
final type).

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.
