Enum TypeData 

pub enum TypeData {
    Struct(StructData),
    Enum(EnumData),
    Array {
        element: InternedType,
        len: u64,
    },
    PtrConst {
        pointee: InternedType,
    },
    PtrMut {
        pointee: InternedType,
    },
}

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

Trait Implementations
