Enum MissReason 

pub enum MissReason {
    NotFound,
    Expired,
    Invalidated,
}

Why a CacheMissEvent fired.

Variants

NotFound

Key was not present in any tier.

Expired

Key was present but the entry’s TTL had elapsed.

Invalidated

Key was explicitly invalidated via crate::resolver::Resolver::invalidate (per-key) or one of the bulk APIs (crate::resolver::Resolver::invalidate_all, crate::resolver::Resolver::invalidate_by_slug, crate::resolver::Resolver::invalidate_by_namespace). Per-key invalidations report Invalidated for the next miss on that exact key; bulk invalidations report Invalidated for the very next miss on any key and then revert to NotFound / Expired reasoning (the resolver doesn’t enumerate every just-evicted key — see the field-level docs on Resolver::recently_invalidated for the rationale).

Trait Implementations

impl Clone for MissReason

fn clone(&self) -> MissReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MissReason

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

Formats the value using the given formatter.

impl PartialEq for MissReason

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