Enum HealthRequest 

pub enum HealthRequest {
    HealthCheck {
        request: HealthCheckRequest,
        responder: HealthHealthCheckResponder,
    },
    #[non_exhaustive]
    _UnknownMethod {
        ordinal: u64,
        method_type: MethodType,
    },
}

Protocol composed into Driver for performing active health checks and receiving proactive health alerts.

Variants

HealthCheck

Requests the driver to perform a self-diagnostic check.

The Driver Host never issues HealthCheck between Driver.Suspend and the completion of Driver.Resume, answering HealthCheckError.INVALID_STATE itself while the driver is suspended or transitioning power states.

Fields

request: HealthCheckRequest

responder: HealthHealthCheckResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

method_type: MethodType
