Struct wasm_encoder::InstanceType

pub struct InstanceType(/* private fields */);

Represents an instance type.

Implementations

impl InstanceType

pub fn new() -> Self

Creates a new instance type.

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

Define a core type in this instance type.

The returned encoder must be used before adding another definition.

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

Define a type in this instance type.

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

Gets the number of instances that have been imported or exported or aliased in this instance type.

pub fn is_empty(&self) -> bool

Returns whether or not this instance type is empty.

pub fn len(&self) -> u32

Returns the number of entries added to this instance types.
