Struct wasm_encoder::ComponentType

pub struct ComponentType { /* private fields */ }

Represents a component type.

Implementations

impl ComponentType

pub fn new() -> Self

Creates a new component type.

pub fn core_type(&mut self) -> CoreTypeEncoder<'_>

Define a core type in this component type.

The returned encoder must be used before adding another definition.

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

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

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

Defines an import in this component type.

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

Defines an export in this component type.

pub fn core_type_count(&self) -> u32

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

pub fn type_count(&self) -> u32

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

pub fn instance_count(&self) -> u32

Gets the number of instances that have been defined in this component type through imports, exports, or aliases.
