Expand description

An abstract heap type.

Variants§

Func

The abstract, untyped (any) function.

Introduced in the references-types proposal.

Extern

The abstract, external heap type.

Introduced in the references-types proposal.

Any

The abstract any heap type.

The common supertype (a.k.a. top) of all internal types.

Introduced in the GC proposal.

None

The abstract none heap type.

The common subtype (a.k.a. bottom) of all internal types.

Introduced in the GC proposal.

NoExtern

The abstract noextern heap type.

The common subtype (a.k.a. bottom) of all external types.

NoFunc

The abstract nofunc heap type.

The common subtype (a.k.a. bottom) of all function types.

Introduced in the GC proposal.

Eq

The abstract eq heap type.

The common supertype of all heap types on which the ref.eq instruction is allowed.

Introduced in the GC proposal.

Struct

The abstract struct heap type.

The common supertype of all struct types.

Introduced in the GC proposal.

Array

The abstract array heap type.

The common supertype of all array types.

Introduced in the GC proposal.

I31

The abstract i31 heap type.

It is not expected that Wasm runtimes actually store these values on the heap, but unbox them inline into the i31refs themselves instead.

Introduced in the GC proposal.

Exn

The abstraction exception heap type.

Introduced in the exception-handling proposal.

NoExn

The abstract noexn heap type.

The common subtype (a.k.a. bottom) of all exception types.

Introduced in the exception-handling proposal.

Cont

The abstract continuation heap type.

Introduced in the stack-switching proposal.

NoCont

The abstract noexn heap type.

The common subtype (a.k.a. bottom) of all continuation types.

Introduced in the stack-switching proposal.
