Enum LookupOutcome 

pub enum LookupOutcome {
    Hit(Payload),
    Miss,
    Invalidated,
}

Variants

Hit(Payload)

Cache hit. The payload is byte-for-byte the same as the original execution and (for revalidating lookups) every file root has been confirmed unchanged.

Miss

No entry for this key.

Invalidated

Entry existed but a file root has changed; the entry has been removed from the registry so subsequent lookups behave as Miss without paying the revalidation cost again.

Trait Implementations

impl Clone for LookupOutcome

fn clone(&self) -> LookupOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LookupOutcome

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

Formats the value using the given formatter.

impl PartialEq for LookupOutcome

fn eq(&self, other: &LookupOutcome) -> 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.
