Struct Page

Source
pub struct Page<TKey, TValue>(/* private fields */);
Expand description

A single page in a Map. Contains up to 256 key-value entries.

Implementations§

Source§

impl<K, V> Page<K, V>
where K: Collapse,

Source

pub const fn new() -> Self

Create a new blank page

Source

pub fn len(&self) -> usize

The number of entries currently in this page

This is a count that iterates over all slots, if possible store it in a temporary instead of re-calling it many times.

Source

pub fn iter(&self) -> PageElements<'_, K, V>

An iterator over all entries currently in this page

Source

pub fn iter_mut(&mut self) -> PageElementsMut<'_, K, V>

A mutable iterator over all entries currently in this page
