Trait HandlerPolicy 

pub trait HandlerPolicy<I> {
    type HandlerId: Copy + Eq + Ord;
    type Abrupt;

    // Required method
    fn handler_for(
        instruction: I,
        abrupt: &Self::Abrupt,
    ) -> Option<Self::HandlerId>;
}

Selects protected regions and consumer-defined abrupt outcomes.

For example, a WebAssembly trap policy or a BEAM exit policy can supply it.

Required Associated Types

type HandlerId: Copy + Eq + Ord

Consumer-defined handler identity.

type Abrupt

Consumer-defined abrupt outcome.

Required Methods

fn handler_for(instruction: I, abrupt: &Self::Abrupt) -> Option<Self::HandlerId>

Finds the handler, if any, for an instruction and abrupt outcome.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
