Struct CacheEvent 

pub struct CacheEvent { /* private fields */ }

Metadata-only cache event.

Implementations

impl CacheEvent

pub fn for_key<I, S>( kind: CacheEventKind, key: impl Into<String>, origin: CacheEventOrigin, tags: I, ) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Create a key-scoped event.

pub fn for_tag( kind: CacheEventKind, tag: impl Into<String>, affected_keys: u64, origin: CacheEventOrigin, ) -> Self

Create a tag-scoped event.

pub fn for_cache( kind: CacheEventKind, affected_keys: Option<u64>, origin: CacheEventOrigin, ) -> Self

Create a cache-wide event.

pub fn kind(&self) -> CacheEventKind

Return the event kind.

pub fn scope(&self) -> &CacheEventScope

Return the event scope.

pub fn origin(&self) -> CacheEventOrigin

Return the event origin.

pub fn key(&self) -> Option<&str>

Return the event key when this is a key-scoped event.

pub fn tag(&self) -> Option<&str>

Return the event tag when this is a tag-scoped event.

pub fn tags(&self) -> &[String]

Return event tags associated with the key or invalidation.

pub fn affected_keys(&self) -> Option<u64>

Return the affected-key count when known.

pub fn timestamp(&self) -> SystemTime

Return the event timestamp.

Trait Implementations

impl Clone for CacheEvent

fn clone(&self) -> CacheEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheEvent

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

Formats the value using the given formatter.

impl Eq for CacheEvent

impl PartialEq for CacheEvent

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