Struct mz_persist_client::inspect::K

pub(crate) struct K;

The following is a very terrible hack that no one should draw inspiration from. Currently State is generic over <K, V, T, D>, with KVD being represented as phantom data for type safety and to detect persisted codec mismatches. However, reading persisted States does not require actually decoding KVD, so we only need their codec names to match, not the full types. For the purposes of persistcli inspect, which only wants to read the persistent data, we create new types that return static Codec names, and rebind the names if/when we get a CodecMismatch, so we can convince the type system and our safety checks that we really can read the data.

fn decode(_buf: &[u8]) -> Result<Self, String>
