Fields

host_exported_func: Box<dyn for<'c> Fn(&mut <WB as WasmBackend>::Caller<'c>, Vec<IValue, Global>) -> Option<IValue> + Sync + Send + 'static, Global>

This closure will be invoked for corresponding import.

argument_types: Vec<IType, Global>

Type of the closure arguments.

output_type: Option<IType>

Types of output of the closure.

error_handler: Option<Box<dyn Fn(&HostImportError) -> Option<IValue> + Sync + Send + 'static, Global>>

If Some, this closure is called with error when errors is encountered while lifting. If None, panic will occur.
