Enum nix::sys::aio::Buffer[−][src]

pub enum Buffer<'a> {
    None,
    Phantom(PhantomData<&'a mut [u8]>),
    BoxedSlice(Box<dyn Borrow<[u8]>>),
    BoxedMutSlice(Box<dyn BorrowMut<[u8]>>),
}

Owns (uniquely or shared) a memory buffer to keep it from Droping while the kernel has a pointer to it.

Variants

None

No buffer to own.

Used for operations like aio_fsync that have no data, or for unsafe operations that work with raw pointers.

Phantom(PhantomData<&'a mut [u8]>)

Keeps a reference to a slice

BoxedSlice(Box<dyn Borrow<[u8]>>)

Generic thing that keeps a buffer from dropping

BoxedMutSlice(Box<dyn BorrowMut<[u8]>>)

Generic thing that keeps a mutable buffer from dropping
