import { pack } from "https://deno.land/x/willow@0.3.5/src/store/storage/kv/key_codec/encoder.ts";
pack() -- the main entry point
Encode the specified item or array of items into a buffer.
pack(x)
is equivalent to pack([x])
if x is not itself an array.
Packing single items this way is also slightly more efficient.
