Trait Counter 

pub trait Counter:
    Send
    + Sync
    + 'static {
    // Required methods
    fn inc(&self);
    fn inc_by(&self, v: u64);
    fn get(&self) -> u64;
}

Single counter handle (one specific label combination).

Required Methods

fn inc(&self)

fn inc_by(&self, v: u64)

Increment the counter by v.

Implementations must use saturating arithmetic: calling inc_by when the counter is at or near its maximum value must not wrap around to zero. Saturation at the maximum representable value is acceptable.

fn get(&self) -> u64

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
