Trait purezen::allocator::Allocator

pub trait Allocator<T: Allocated>: Index<T::Id> + IndexMut<T::Id> {
    fn allocate<F>(&mut self, f: F) -> &mut T
    where
        F: Fn(T::Id) -> T;
    fn get(&self, id: T::Id) -> Option<&T>;
    fn get_mut(&mut self, id: T::Id) -> Option<&mut T>;
}

Indexed memory allocator providing O(1) access to contained values by a T::Id type.

Required methods

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 an object located at the given slot ID.

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

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