[−][src]Crate reusable_memory

To reuse memory, it needs to be allocated first:

let mut memory: ReusableMemory<u8> = ReusableMemory::new().unwrap();

new will return an Err if the generic type passed to ReusableMemory is a zero sized type.

The memory can then be borrowed as a different type:

let mut borrowed_memory = memory.borrow_mut_as::<usize>(NonZeroUsize::new(3).unwrap()).unwrap();

borrow_mut_as will return an Err if the generic type passed is a zero sized type.

Now borrowed_memory holds a pointer to enough memory to store 3 properly-aligned usizes inside the memory allocated in memory.

borrowed_memory.push(1).unwrap();
borrowed_memory.push(2).unwrap();
borrowed_memory.push(std::usize::MAX).unwrap();

push will return an Err if the pushed value would not fit into the capacity of the borrowed memory.

The borrowed memory is automatically returned when the object is dropped, and the pushed values are dropped as well.
