Enum MissReason 

pub enum MissReason {
    ValueAbsent,
    Expired,
    WatermarkFenced,
    Unclassified,
}

Bounded cause of a semantic miss.

Variants

ValueAbsent

The layer had no retrievable value.

Expired

A valid frame’s logical age reached its ceiling.

WatermarkFenced

A tracked frame was rejected by an invalidation watermark.

Unclassified

A real miss with no decisive cause: malformed frames, unknown replies, invalid or future timestamps, decode failures.

Implementations

impl MissReason

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

The snake_case label value shared with the TypeScript and Go ports.

pub fn parse(text: &str) -> Option<Self>

The inverse of as_str. None for any other text, which callers treat as MissReason::Unclassified.

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 Copy for MissReason

impl Debug for MissReason

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MissReason

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MissReason

impl Hash for MissReason

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 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.

impl Serialize for MissReason

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
