Trait Signaller 

pub trait Signaller<Hash>
where
    Hash: Encode + Decode + Debug + Clone + PartialEq + Eq,
{
    type Result;

    // Required method
    fn signal(signal: &ExecutionSignal<Hash>) -> Self::Result;
}

This trait provides access for a provider to send/recieve signals. This is a bidirectional trait, both 3vm & sdk implement a variant of this with a differing error type.

This enables a contract to provide some feedback to the circuit and tell it if it should break or not. This also allows a pallet to enable signalling.

Required Associated Types

type Result

Required Methods

fn signal(signal: &ExecutionSignal<Hash>) -> Self::Result

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.
