Struct RingMmap

Source 
pub struct RingMmap<T> {
    pub mmap: OwnedMmap,
    pub producer: *mut AtomicU32,
    pub consumer: *mut AtomicU32,
    pub desc: *mut T,

}
Expand description

Holds the raw memory-mapped components of a ring buffer.

This struct contains raw pointers to the producer/consumer indices, the descriptor array, and flags within the memory-mapped region. It is managed by the Ring struct.

Fields§

§mmap: OwnedMmap

The memory-mapped region owned by this struct.

§producer: *mut AtomicU32

A pointer to the atomic producer index of the ring.

§consumer: *mut AtomicU32

A pointer to the atomic consumer index of the ring.

§desc: *mut T

A pointer to the beginning of the descriptor array.

§flags: *mut AtomicU32

A pointer to the atomic flags field of the ring.
