Enum TypeDef

source
pub enum TypeDef {
    Component(TypeComponentIndex),
    ComponentInstance(TypeComponentInstanceIndex),

Expand description

Types of imports and exports in the component model.

These types are what’s available for import and export in components. Note that all indirect indices contained here are intended to be looked up through a sibling ComponentTypes structure.

Variants§

§

Component(TypeComponentIndex)

A component and its type.

§

ComponentInstance(TypeComponentInstanceIndex)

An instance of a component.

§

ComponentFunc(TypeFuncIndex)

A component function, not to be confused with a core wasm function.

§

Interface(InterfaceType)

An type in an interface.

§

Module(TypeModuleIndex)

A core wasm module and its type.

§

CoreFunc(ModuleInternedTypeIndex)

A core wasm function using only core wasm types.

§

Resource(TypeResourceTableIndex)

A resource type which operates on the specified resource table.

Note that different resource tables may point to the same underlying actual resource type, but that’s a private detail.
