Enum Freshness 

pub enum Freshness {
    Fresh,
    Unknown,
    Stale,
}

How fresh a positive verdict is, relative to the verifier’s freshness policy. A positive verdict is never bare: it is always qualified by one of these.

Variants

Fresh

The supplied freshness evidence is within the policy window.

Unknown

No source fresher than the supplied slice was available (offline). The verdict is valid as-of its bound, but freshness cannot be confirmed — this is named, never a silent pass and never a hard reject.

Stale

The supplied freshness evidence is provably older than the policy window.

Trait Implementations

impl Clone for Freshness

fn clone(&self) -> Freshness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Freshness

impl Debug for Freshness

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

Formats the value using the given formatter.

impl Default for Freshness

fn default() -> Self

Offline-unknown is the safe default: absent any fresher-source evidence, a verdict’s freshness cannot be confirmed, so it is named Freshness::Unknown — never silently treated as fresh. This is what #[serde(default)] resolves a missing field to.

impl<'de> Deserialize<'de> for Freshness

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Freshness

impl PartialEq for Freshness

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Freshness

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
