Enum SavedSnapshot 

pub enum SavedSnapshot {
    None,
    Current,
    Fallback,
    Unreadable,
}

PROP_SAVED: what the device reports about its stored snapshot.

The two failure values are the point of the property. An unattended repeater that comes back on stale configuration, or on none at all, looks identical to a healthy one from the outside — this is how a host that does eventually attach finds out.

Variants

None

Nothing is saved.

Current

The newest saved generation is in effect.

Fallback

A newer generation was rejected at boot and an older one is in effect: the device is working, on stale configuration. Re-save to clear it.

Unreadable

A snapshot exists but no generation could be read; the device booted with post-reset defaults.

Implementations

impl SavedSnapshot

pub fn is_saved(self) -> bool

Whether a saved snapshot is in effect at all, in either generation.

Trait Implementations

impl Clone for SavedSnapshot

fn clone(&self) -> SavedSnapshot

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SavedSnapshot

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SavedSnapshot

fn eq(&self, other: &SavedSnapshot) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
