Expand description

An external value is the runtime representation of an entity that can be imported or exported.

Variants

Func(FuncRef)

Table(TableRef)

Memory(MemoryRef)

Global(GlobalRef)

Global.

Should be immutable.

Implementations

Get underlying function reference if this ExternVal contains a function, or None if it is some other kind.

Get underlying table reference if this ExternVal contains a table, or None if it is some other kind.

Get underlying memory reference if this ExternVal contains a memory, or None if it is some other kind.

Get underlying global variable reference if this ExternVal contains a global, or None if it is some other kind.
