pub const WIRE_SIZE: &'static str;Expand description
Metadata key carrying the true on-wire byte size (as an i64) of a
dora topic debug frame’s data sample.
The daemon rebuilds a self-describing Arrow IPC stream for inspection by
prepending the retained schema block to each schema-once batch, so the
rebuilt stream the CLI receives is larger than what actually travelled on
the wire (the schema-less batch — the schema is published only once on the
@schema subtopic). To keep dora topic info’s bandwidth accounting
accurate, the daemon stamps the original data-sample length here; the CLI
measures this instead of the rebuilt stream length (dora-rs/dora#2584).
Debug/inspection path only — never set on real node→node outputs.
