Variants

Insert

Fields

key: K

value: V

source: Option<Uuid>

Update

Fields

key: K

old_value: Option<V>

What was there before. Bytes that will not read as V fall back to what the map last held, so a key it knows always carries one.

new_value: V

source: Option<Uuid>

Remove

Fields

key: K

old_value: Option<V>

source: Option<Uuid>

Clear

Fields

source: Option<Uuid>
