Expand description

A reason why a VCPU exited. One of these returns every time Vcpu::run is called.

Variants§

§

Io

An io instruction needs to be emulated. vcpu handle_io should be called to handle the io operation

§

Mmio

A mmio instruction needs to be emulated. vcpu handle_mmio should be called to handle the mmio operation

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
