Struct SegmentMeta 

Source 
#[repr(C, align(64))]
pub struct SegmentMeta {
    pub segment_id: IndexbusAtomicU32,

Expand description

Journal segment metadata for one journal segment.

Kept 64B-aligned so per-segment metadata can be read without false sharing.

Fields§

§segment_id: IndexbusAtomicU32

Segment identifier (implementation-defined).

§segment_len: IndexbusAtomicU32

Segment length in bytes.

§tail: IndexbusAtomicU64

Tail cursor within the segment.

§pad_to_64: [u8; 48]

Padding to keep segment metadata in a cache line.
