Struct InstanceId 

pub struct InstanceId {
    pub map_id: u64,
    pub ns: Option<u64>,
}

The complete public identity of a collection instance — the same shape at every layer: in-memory comparison, the persisted meta bytes, and this token. ns: None ⇔ default namespace ⇔ the 16-byte meta form; a bare u64 converts losslessly (From<u64> ⇒ ns: None).

Display/FromStr round-trip as "42" (default ns) or "42@7" (ns 7) — config/log friendly.

Canonical form: the default namespace is spelled ns: None, never Some(DEFAULT_NS_ID). Every constructor under this type’s control (From<u64>, FromStr, Deserialize, and the handles’ instance_id()) canonicalizes, so Eq/Hash are reliable for tokens obtained through the API. Routing treats both spellings as the default namespace regardless.

Fields

map_id: u64

The storage prefix — what pre-v16 releases called instance_id.

ns: Option<u64>

The owning namespace; None = default namespace (canonical — see the type docs).

Implementations

impl InstanceId

pub fn new(map_id: u64, ns: u64) -> InstanceId

Canonical constructor: DEFAULT_NS_ID folds to ns: None. The single construction point handles use — keeps canonical-form logic out of every call site.
