pub const SCHEMA_HASH: &'static str;Expand description
Metadata key carrying the FNV-1a hash (as an i64) of the Arrow IPC schema
for a zenoh data message. Present on schema-once messages so a receiver can
tell which primed decoder a schema-less batch belongs to and detect schema
changes. Absent on messages a receiver should decode as a standalone full
stream (large/SHM and daemon-path payloads).
