Struct GaugeF64 

pub struct GaugeF64 { /* private fields */ }

A cache-padded atomic gauge for floating-point point-in-time measurements.

Uses AtomicU64 to store the bit representation of an f64, enabling atomic operations on floating-point values.

Usage

Use this for metrics that require decimal precision, such as:

• Memory usage in MB/GB
• CPU utilization percentages
• Ratios and rates

For integer values, prefer Gauge which uses i64 directly.

Implementations

impl GaugeF64

pub fn new() -> Self

Create a new gauge initialized to zero.

pub fn set(&self, value: f64)

Set the gauge to a value.

pub fn get(&self) -> f64

Get the current value.
