Implementations

impl ComponentType

pub fn new() -> Self

Available on crate feature component-model only.

pub fn ty(&mut self) -> ComponentTypeEncoder<'_>

Available on crate feature component-model only.

Define a type in this component type.

The returned encoder must be used before adding another definition.

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

Available on crate feature component-model only.

Defines an alias for an exported item of a prior instance or an outer type.

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

Available on crate feature component-model only.

Defines an import in this component type.

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

Available on crate feature component-model only.

Defines an export in this component type.

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

pub fn type_count(&self) -> u32

Available on crate feature component-model only.

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

pub fn instance_count(&self) -> u32

Available on crate feature component-model only.
