Struct ShmRingMetadata 

pub struct ShmRingMetadata {
    pub name: String,
    pub segment_size: usize,
    pub format_version: u32,
    pub kind: u8,
    pub spec: RingSpec,
    pub lane_count: usize,
}

Persisted geometry of one existing Orbit SHM ring.

The values come from the mapped ring header. An observer does not need the producer’s fleet capacity or compile-time RingSpec to inspect raw frames.

Fields

name: String

Exact POSIX SHM object name that was opened.

segment_size: usize

Number of bytes reported by the existing SHM object.

format_version: u32

Persisted Orbit ring format version.

kind: u8

Stable Orbit type kind carried by this ring.

spec: RingSpec

Persisted per-lane capacity, payload limit, and topology.

lane_count: usize

Number of physical lanes present in the mapping.
