Enum pingora_cache::CachePhase

pub enum CachePhase {
    Disabled(NoCacheReason),
    Uninit,
    Bypass,
    CacheKey,
    Hit,
    Miss,
    Stale,
    Expired,

}

This reflects the phase of HttpCache during the lifetime of a request

Variants

Disabled(NoCacheReason)

Cache disabled, with reason (NeverEnabled if never explicitly used)

Uninit

Cache enabled but nothing is set yet

Bypass

Cache was enabled, the request decided not to use it

CacheKey

Awaiting the cache key to be generated

Hit

Cache hit

Miss

No cached asset is found

Stale

A staled (expired) asset is found

Expired

A staled (expired) asset was found, so a fresh one was fetched

Revalidated

A staled (expired) asset was found, and it was revalidated to be fresh

RevalidatedNoCache(NoCacheReason)

Revalidated, but deemed uncacheable, so we do not freshen it

Implementations

impl CachePhase

pub fn as_str(&self) -> &'static str

Convert CachePhase as str, for logging and debugging.

Trait Implementations

impl Clone for CachePhase

fn clone(&self) -> CachePhase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CachePhase

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

Formats the value using the given formatter.

impl PartialEq for CachePhase

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

This method tests for self and other values to be equal, and is used by ==.

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

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