//! `rewrite_fmt` for the 500-LOC house rule.

/// Emit one (or two, if TTL'd) RESP write commands that, when replayed,
/// reconstruct `key`'s `value` and TTL exactly, into a fresh buffer in

///
/// The rewrite path calls the writer below directly. This wrapper is for
/// callers that need the *commands* rather than an AOF file: the
/// cross-shard RENAME has to record the value it just placed on another
/// shard, and reproducing the per-type mapping there would be a second
/// implementation of the one thing `BGREWRITEAOF` already has to get
/// right for every `Value` variant, TTL and stream shape.
