Required Methods§

source

fn call( &self, ext: &mut dyn Externalities, runtime_code: &RuntimeCode<'_>, method: &str, data: &[u8], use_native: bool, context: CallContext ) -> (Result<Vec<u8>, Self::Error>, bool)

Call a given method in the runtime.

Returns a tuple of the result (either the output data or an execution error) together with a bool, which is true if native execution was used.
