Trait Implementations

source

impl<K, V> CountableMeterWithMeasure<K, V, ()> for Count

source

fn meter_add(&self, _current: (), _amount: ())

Add amount to current and return the sum.

source

fn meter_sub(&self, _current: (), _amount: ())

Subtract amount from current and return the difference.

source

fn meter_size(&self, _current: ()) -> Option<u64>

Return current as a usize if possible, otherwise return None. Read more

source

impl<K, V> Meter<K, V> for Count

type Measure = ()

Don’t store anything, the measurement can be derived from the map.

source

fn measure<Q: ?Sized>(&self, _: &Q, _: &V) where
K: Borrow<Q>,

Don’t actually count anything either.
