pub struct PerVcpuState {
    pause_request: Option<u64>,
}
Expand description

State specific to a VCPU, grouped so that each PluginVcpu object will share a canonical version.

Fields§

§pause_request: Option<u64>

Implementations§

Indicates that a VCPU should wait until the plugin process resumes the VCPU.

This method will not cause a VCPU to pause immediately. Instead, the VCPU thread will continue running until a interrupted, at which point it will check for a pending pause. If there is another call to request_pause for this VCPU before that happens, the last pause request’s data will be overwritten with the most recent `data.

To get an immediate pause after calling request_pause, send a signal (with a registered handler) to the thread handling the VCPU corresponding to this state. This should interrupt the running VCPU, which should check for a pause with PluginVcpu::pre_run.

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.
Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

Returns the argument unchanged.
