Enum HardwareProbe 

#[non_exhaustive]
pub enum HardwareProbe {
    Available(HardwareKind),
    Absent,
    Indeterminate {
        detail: String,
    },
}

The result of asking a host whether it has a usable hardware trusted component.

Three-valued on purpose. See the module docs: Absent and Indeterminate are different facts and must not be collapsed.

#[non_exhaustive]: a future probe may report a state these three do not cover, and that must not be a breaking change.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Available(HardwareKind)

Hardware of this class is present and reachable.

Absent

Definitively no usable hardware on this host.

Indeterminate

The probe itself failed — availability is unknown.

Fields

detail: String

Non-secret detail of the probe failure.
