Struct SpscRingHeader 

pub struct SpscRingHeader {
    pub visible_head: AtomicU64,
    pub tail: AtomicU64,
    pub capacity: u32,
    /* private fields */
}

SPSC ring header (192 bytes, cache-line aligned fields).

Fields

visible_head: AtomicU64

tail: AtomicU64

Consumer index (written by consumer, read by producer).

capacity: u32

Ring capacity (power of 2, immutable after init).

Implementations
