Enum ExtFunctionResult 

pub enum ExtFunctionResult {
    Return(MontyObject),
    Error(MontyException),
    Future(u32),
    NotFound(String),
}

Return value or exception from an external function.

Variants

Return(MontyObject)

Continues execution with the return value from the external function.

Error(MontyException)

Continues execution with the exception raised by the external function.

Future(u32)

Pending future — the external function is a coroutine.

The u32 is the call_id from the FunctionCall that created this snapshot. It is used to track the pending future so it can be resolved later via ResolveFutures::resume().

NotFound(String)

The function was not found, should result in a NameError exception.
