A unified type definition for validating WebAssembly modules and components.

Variants

Sub(SubType)

The definition is for a sub type.

Module(Box<ModuleType, Global>)

The definition is for a core module type.

This variant is only supported when parsing a component.

Instance(Box<InstanceType, Global>)

The definition is for a core module instance type.

This variant is only supported when parsing a component.

Component(Box<ComponentType, Global>)

The definition is for a component type.

This variant is only supported when parsing a component.

ComponentInstance(Box<ComponentInstanceType, Global>)

The definition is for a component instance type.

This variant is only supported when parsing a component.

ComponentFunc(ComponentFuncType)

The definition is for a component function type.

This variant is only supported when parsing a component.

Defined(ComponentDefinedType)

The definition is for a component defined type.

This variant is only supported when parsing a component.

Resource(ResourceId)

This definition is for a resource type in the component model.

Each resource is identified by a unique identifier specified here.

Implementations

impl Type

pub fn unwrap_func(&self) -> &FuncType
