Struct LiteralCounters 

pub struct LiteralCounters { /* private fields */ }

Available on crate features std and ua only.

Implementations

impl LiteralCounters

pub fn new(capacity: usize) -> LiteralCounters

pub fn from_snapshot( snapshot: &CounterSnapshot, capacity: usize, ) -> Result<LiteralCounters, ProfileDataError>

Validate every count and the full accounting identity before retaining keys.

pub fn snapshot(&self) -> CounterSnapshot

pub fn observe(&mut self, value: ValueId) -> Result<(), ProfileDataError>

The ingestion transaction admits the ID and validates/interns the value first. Counter overflow leaves this accumulator unchanged.

pub fn observe_unretained( &mut self, value: ValueId, reason: ObservationLoss, ) -> Result<(), ProfileDataError>

Record a validated observation without retaining its literal or sample.

pub fn untracked_distinct(&self) -> UntrackedDistinctCount

pub fn weight(&self, value: ValueId) -> ObservationWeight

pub fn merge( &self, other: &LiteralCounters, ) -> Result<LiteralCounters, ProfileDataError>

Merge disjoint observations into the same bottom-k literal budget.

pub fn coarsen( &self, other: &LiteralCounters, ) -> Result<LiteralCounters, ProfileDataError>

Coarsening retains every known per-value count from disjoint time buckets.

Trait Implementations

impl Clone for LiteralCounters

fn clone(&self) -> LiteralCounters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LiteralCounters

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

Formats the value using the given formatter.
