A trait for Gauges
Required Methods
Increment the gauge by count in one step
Supplying a count larger than the underlying counter’s remaining
capacity will wrap like u8::wrapping_add and similar methods.
Decrement the gauge by count in one step
Supplying a count larger than the underlying counter’s current value
will wrap like u8::wrapping_sub and similar methods.
