The returned encoder must be used before adding another definition.

pub fn alias(&mut self, alias: Alias<'_>) -> &mut Self

Defines an outer core type alias in this component type.

pub fn export(&mut self, name: &str, ty: ComponentTypeRef) -> &mut Self

Defines an export in this instance type.

pub fn core_type_count(&self) -> u32

Gets the number of core types that have been added to this instance type.

pub fn type_count(&self) -> u32

Gets the number of types that have been added or aliased in this instance type.

pub fn instance_count(&self) -> u32
