pub struct WasmSubType {
pub is_final: bool,
pub supertype: Option<EngineOrModuleTypeIndex>,
pub composite_type: WasmCompositeType,
}
Expand description
A concrete, user-defined (or host-defined) Wasm type.
Fields§
§is_final: bool
Whether this type is forbidden from being the supertype of any other type.
supertype: Option<EngineOrModuleTypeIndex>
This type’s supertype, if any.
composite_type: WasmCompositeType
The array, function, or struct that is defined.
Implementations§
source§impl WasmSubType
impl WasmSubType
Implicitly define all of these helper functions to handle only unshared
types; essentially, these act like is_unshared_*
functions until shared
support is implemented.
