Function parse_command 

Source 
pub fn parse_command(
    buf: &[u8],
) -> Result<Option<(Command, usize)>, ProtocolError>
Expand description

Attempt to parse one command from the front of buf.

  • Ok(Some((cmd, consumed))) — a full command; consumed bytes may be dropped.
  • Ok(None) — need more bytes; call again after reading more.
  • Err(_) — the stream is corrupt; the caller should reply with an error and close the connection.

This is the convenience form that allocates a fresh Argv per call. The reactor’s hot path uses parse_command_into with a reused scratch Argv to keep per-cmd malloc rate at 0.
