Struct TypePools

pub struct TypePools<H = RandomState> { /* private fields */ }

A collection of pools or arrays that contain values of a specific type

Implementations

impl TypePools

pub fn new() -> Self

pub fn type_pool<T: 'static>(&self) -> Option<&TypePool<T>>

Get a reference to a type pool

pub fn type_pool_mut<T: 'static>(&mut self) -> Option<&mut TypePool<T>>

Get a mutable reference to a type pool

pub fn push<T: 'static>(&mut self, value: T)

Add a value to the pools. If the type pool doesn’t exst yet, it will be created

pub fn pop<T: 'static>(&mut self) -> Option<T>

Returns the popped item or None if the value doesn’t exist

pub fn remove<T: 'static>(&mut self, idx: usize) -> Option<T>

Remove the value at the index in the type pool specified by T

pub fn get<T: 'static>(&self, idx: usize) -> Option<&T>

Gets a value from a TypePool

Parameters

• idx: this is the index in the specific type T array

pub fn get_mut<T: 'static>(&mut self, idx: usize) -> Option<&mut T>

Get a mutable reference to a value in a TypePool

pub fn len<T: 'static>(&self) -> Option<usize>

pub fn types_count(&self) -> usize

The amount of types stored in pools

pub fn types(&self) -> Vec<&TypeId>

The types stored in pools

pub fn remove_type<T: 'static>(&mut self)

Remove all entries for a type

pub fn remove_empty(&mut self)

Remove all types which do not contain any values

pub fn shrink_to_fit(&mut self)

Shrink the array containing all the pools to fit
