pub fn with_value(shard_count: usize, initial: f64) -> Self

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

pub fn observe(&self, value: f64)

Record a candidate value for the maximum.

NaN is ignored.

pub fn get(&self) -> f64

Return the current maximum across all shards.

pub fn reset(&self)

Reset all shards to the original value configured at construction.

pub fn swap_reset(&self) -> f64

Reset all shards and return the previous maximum.
