Fields§
§host_exported_func: Box<dyn for<'c> Fn(&mut <WB as WasmBackend>::ImportCallContext<'c>, Vec<IValue>) -> Option<IValue> + Send + Sync>
This closure will be invoked for corresponding import.
argument_types: Vec<IType>
Type of the closure arguments.
output_type: Option<IType>
Types of output of the closure.
error_handler: Option<Box<dyn Fn(&HostImportError) -> Option<IValue> + Send + Sync>>
If Some, this closure is called with error when errors is encountered while lifting. If None, panic will occur.
