Code execution engine.

Required Associated Types

type Error: Display + Debug + Send + Sync + 'static

Externalities error type.

Required Methods

fn call( &self, ext: &mut dyn Externalities, runtime_code: &RuntimeCode<'_>, method: &str, data: &[u8], 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.

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

Call a given method in the runtime, interrupting execution once timeout has elapsed.

Returns the result: either the output data or an execution error, including one indicating that the timeout has been reached.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
