Enum CardEventKind 

pub enum CardEventKind {
    Created,
    Appended,
    SamplesWritten,
    AliasesWritten,
}

Lightweight discriminant for CardEvent. Used as a HashMap key in SubscriberStats so that ok/err counters can be tracked per event kind without holding the full payload.

Implementations

impl CardEventKind

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

Stable string tag used in tracing log fields.

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

Short JSON key for the public alc_stats snapshot. Distinct from as_str() so that tracing logs keep their verbose form while the JSON surface stays compact.

pub fn all() -> [CardEventKind; 4]

All kinds in stable display order. Used by SubscriberHealthRow to emit all four counter keys even when a counter is zero, so that downstream consumers can rely on field presence.

Trait Implementations

impl Clone for CardEventKind

fn clone(&self) -> CardEventKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CardEventKind

impl Debug for CardEventKind

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

Formats the value using the given formatter.

impl Eq for CardEventKind

impl Hash for CardEventKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CardEventKind

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

impl Serialize for CardEventKind

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
