Trait HyperLogLog

pub trait HyperLogLog<H: Hash + ?Sized> {
    // Required methods
    fn add(&mut self, value: &H);
    fn insert<Q>(&mut self, value: &Q)
       where H: Borrow<Q>,
             Q: Hash + ?Sized;
    fn count(&mut self) -> f64;
}

A trait that should be implemented by any HyperLogLog variant.

Required Methods

fn add(&mut self, value: &H)

👎Deprecated since 0.3.0: use insert() function instead.

Adds a new value to the multiset.

fn insert<Q>(&mut self, value: &Q)

where H: Borrow<Q>, Q: Hash + ?Sized,

Inserts a new value to the multiset.

fn count(&mut self) -> f64

Estimates the cardinality of the multiset.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
