Enum witx::Type

pub enum Type {
    Record(RecordDatatype),
    Variant(Variant),
    Handle(HandleDatatype),
    List(TypeRef),
    Pointer(TypeRef),
    ConstPointer(TypeRef),
    Builtin(BuiltinType),
}

Structure of all possible interface types.

Note that this is intended to match the interface types proposal itself. Currently this is relatively close to that with just a few *.witx extensions for now.

Variants

Record(RecordDatatype)

A structure with named field.

Variant(Variant)

An enumeration where a value is one of a number of variants.

Handle(HandleDatatype)

A “handle” which is an un-forgeable reference. Today this is an i32 where a module can’t forge and use integers it was not already given access to.

List(TypeRef)

A list of a type, stored in linear memory.

Note that lists of char are specialized to indicate strings.

Pointer(TypeRef)

A witx-specific type representing a raw mutable pointer into linear memory

ConstPointer(TypeRef)

A witx-specific type representing a raw const pointer into linear memory

Builtin(BuiltinType)

A builtin base-case type.
