Expand description

Type data stored in the intern pool.

This is NOT Copy - it lives in the pool. You work with InternedType indices.

§Type Categories

Struct and Enum are nominal types: identity comes from the name
Array, PtrConst, and PtrMut are structural types: identity comes from element/pointee type

Variants§

Struct(StructData)

User-defined struct (nominal type).

Two structs with the same fields but different names are different types.

Enum(EnumData)

User-defined enum (nominal type).

Two enums with the same variants but different names are different types.

Array

Fixed-size array (structural type).

Arrays with the same element type and length are the same type, regardless of where they were defined.

Fields

§element: InternedType

§len: u64

PtrConst

Raw const pointer (structural type).

ptr const T - pointer to immutable data.

Fields

§pointee: InternedType

PtrMut

Raw mut pointer (structural type).

ptr mut T - pointer to mutable data.

Fields

§pointee: InternedType

Ref

Immutable reference (structural type, ADR-0062).

Ref(T) - scope-bound non-mutating borrow.

Fields

§referent: InternedType

MutRef

Mutable reference (structural type, ADR-0062).

MutRef(T) - scope-bound exclusive mutating borrow.

Fields

§referent: InternedType

Slice

Immutable slice (structural type, ADR-0064).

Slice(T) - scope-bound fat pointer {ptr, len}.

Fields

§element: InternedType

MutSlice

Mutable slice (structural type, ADR-0064).

MutSlice(T) - scope-bound exclusive fat pointer {ptr, len}.

Fields

§element: InternedType

Vec

Owned, growable vector (structural type, ADR-0066).

Vec(T) - heap-allocated {ptr, len, cap}.

Fields

§element: InternedType
