Struct bobbytables::Counter

pub struct Counter { /* fields omitted */ }

The public Counter structure which contains the inner mutable state. This allows us to put this straight into an Arc and safely share between threads

Methods

impl Counter

fn new() -> Counter

Create a new counter, which is has an UnsafeCell wrapping the actual counter implementation.

fn incr(&self, key: &str, count: usize) -> usize

Extract the mutable reference to the counter implementation and increment the given key.

fn get(&self, key: &str) -> usize

Extract the mutable reference to the counter implementation and return the current counter value for the given key.

fn get_index(&self, index: usize) -> Option<(String, usize)>

fn size(&self) -> usize

Trait Implementations

impl<'a> IntoIterator for &'a Counter

type Item = (String, usize)

The type of the elements being iterated over.

type IntoIter = CounterIterator<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
