Struct slab::Slab

pub struct Slab<T, I: Index> {
    // some fields omitted
}

A preallocated chunk of memory for storing objects of the same type.

Methods

impl<T, I: Index> Slab<T, I>

fn new(cap: usize) -> Slab<T, I>

fn new_starting_at(offset: I, cap: usize) -> Slab<T, I>

fn count(&self) -> usize

fn is_empty(&self) -> bool

fn remaining(&self) -> usize

fn has_remaining(&self) -> bool

fn contains(&self, idx: I) -> bool

fn get(&self, idx: I) -> Option<&T>

fn get_mut(&mut self, idx: I) -> Option<&mut T>

fn insert(&mut self, val: T) -> Result<I, T>

fn insert_with<F>(&mut self, f: F) -> Option<I> where F: FnOnce(I) -> T

Like insert but for objects that require newly allocated usize in their constructor.

fn remove(&mut self, idx: I) -> Option<T>

Releases the given slot

fn replace(&mut self, idx: I, t: T) -> Option<T>

fn iter(&self) -> SlabIter<T, I>
