Struct purezen::allocator::FixedSizeAllocator

pub struct FixedSizeAllocator<T: Allocated, N: ArrayLength<Option<T>>> { /* fields omitted */ }

Allocator with a fixed-size buffer for use in no_std environments

Methods

impl<T, N> FixedSizeAllocator<T, N> where
    T: Allocated,
    N: ArrayLength<Option<T>>, 

pub fn new(label: &'static str) -> Self

Create a new state object, initialized to the default state

pub fn iter_mut(&mut self) -> IterMut<T>

Iterate over the contents of this allocator mutably

Trait Implementations

impl<T, N> Allocator<T> for FixedSizeAllocator<T, N> where
    T: Allocated,
    N: ArrayLength<Option<T>>, 

Important traits for &'_ mut I

impl<'_, I> Iterator for &'_ mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

fn allocate<F>(&mut self, f: F) -> &mut T where
    F: Fn(T::Id) -> T, 

Allocate a slot in the buffer and call the given function to get a value

Panics if there is no space available in the buffer.

fn get(&self, id: T::Id) -> Option<&T>

Get value located at the given slot ID.

fn get_mut(&mut self, id: T::Id) -> Option<&mut T>

Get a mutable reference to an value located at the given slot ID.

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
