Struct MinGauge 

pub struct MinGauge { /* private fields */ }

A thread-sharded minimum tracker exported as a gauge.

Implementations

impl MinGauge

pub fn new(shard_count: usize) -> Self

Create a new min gauge with all shards initialized to i64::MAX, so any observation displaces the initial value.

get() on a gauge that has never been observed returns i64::MAX; callers that need a different sentinel should use Self::with_value.

pub fn with_value(shard_count: usize, initial: i64) -> Self

Create a new min gauge with all shards initialized to initial.

pub fn observe(&self, value: i64)

Record a candidate value for the minimum.

pub fn get(&self) -> i64

Return the current minimum across all shards.

pub fn reset(&self)

Reset all shards to the original value configured at construction.

pub fn swap_reset(&self) -> i64

Reset all shards and return the previous minimum.
