pub fn parse_command_borrowed(
buf: &[u8],
) -> Result<Option<(ArgvBorrowed<'_>, usize)>, ProtocolError>Expand description
Parse one command from the front of buf, recording each arg as a
(start, end) range into buf rather than copying its bytes.
The returned ArgvBorrowed is a zero-copy view: get(i) slices directly
into buf. Use this on the local single-shard hot path; call
ArgvBorrowed::into_owned before storing an argv past the buffer’s
lifetime (cross-shard dispatch, MULTI queue, AOF logging).
Return shape matches crate::parse_command: Ok(Some((argv, consumed))),
Ok(None) if more bytes are needed, Err on malformed input.
