Enum CapabilityState 

pub enum CapabilityState {
    Available,
    Unsupported,
    PermissionDenied,
    Unknown,
}

Whether one capability is usable on this system.

Variants

Available

Present and readable.

Unsupported

This platform or kernel does not provide it.

PermissionDenied

Present but the OS refuses the read at our privilege level.

Distinct from Unsupported because §4 requires a help hint suggesting what elevated privileges would provide.

Unknown

Not probed yet.

Implementations

impl CapabilityState

pub const fn label(self) -> &'static str

Lower-case label for the Inspect screen.

pub const fn symbol(self) -> char

A redundant non-color cue (§5.2).

pub const fn privileges_might_help(self) -> bool

Whether elevated privileges would plausibly help.

Drives the help hint §4 requires. Note that §15.1 forbids monitrs from escalating on its own; this only informs the user.
