Counter

Struct Counter 

Source
pub struct Counter {
    pub count: AtomicU64,
    pub ticks: AtomicU64,
}
Expand description

The standard atomic counter implementation for timed_span!.

count records the number of timed spans, while ticks accumulates their elapsed processor-counter ticks (or nanoseconds on unsupported architectures). Use this type when a total, a count, and their derived average are sufficient.

Fields§

§count: AtomicU64§ticks: AtomicU64

Implementations§

Source§

impl Counter

Source

pub const fn new() -> Self

Creates a counter with both measurements set to zero.

Source

pub fn reset(&self)
