Struct SharedMemAllocatorDropGuard

pub struct SharedMemAllocatorDropGuard(/* private fields */);

The intended singleton destructor for the global singleton shared memory allocator.

Because the global allocator has static lifetime, drop() will never be called on it. Therefore, necessary cleanup routines are not called. Instead, this object can be instantiated once, eg at the start of main(), and then when it is dropped at program exit the cleanup routine is called.

Implementations

impl SharedMemAllocatorDropGuard

pub unsafe fn new() -> Self

Safety

Must outlive all ShMemBlock objects allocated by the current process.

Trait Implementations

impl Drop for SharedMemAllocatorDropGuard

fn drop(&mut self)
