Trait coca::storage::Storage

pub unsafe trait Storage<R: LayoutSpec>: Sized {
    fn get_ptr(&self) -> *const u8;
    fn get_mut_ptr(&mut self) -> *mut u8;
    fn capacity(&self) -> usize;
}

An interface to a contiguous memory block for use by data structures.

Required methods

fn get_ptr(&self) -> *const u8

Extracts a pointer to the beginning of the memory block.

Safety

Implementors must ensure the same pointer is returned every time this method is called throughout the block’s lifetime.

fn get_mut_ptr(&mut self) -> *mut u8

Extracts a mutable pointer to the beginning of the memory block.

Safety

Implementors must ensure the same pointer is returned every time this method is called throughout the block’s lifetime.

fn capacity(&self) -> usize

Returns the maximum number of items the memory block can hold.

Safety

What exactly constitutes an item depends on the argument type R. When called on a memory block with a layout matching R::layout_with_capacity(n), this must return at most n.

Implementors must ensure the same value is returned every time this method is called throughout the block’s lifetime.
