## Description Currently, the name of `bucket` is a bit confusing, because it is considered a 'table' in literature (as well as the whole hash table). A `bucket` is better described as a 'subtable', which is used by the total hash table to perform cuckoo hashing. In addition, the constructors `NewTable`, `NewTableBy`, and `NewCustomTable` were given shorter names, because the package name `cuckoo` already implies that `New*` would create a hash table with cuckoo hashing. This package has one use-case, and so it unambiguous what constructors produce. ## Changes - `NewTable` -> `New` - `NewTableBy` -> `NewBy` - `NewCustomTable` -> `NewCustom` - `bucket` -> `subtable` ### Design Decisions - I would have renamed `Table` and `subtable` to map equivalents, but 'submap' implies that a certain subsection of the map is contained within it, which isn't quite right. - I chose not to go with `Map` and `table`, because of the split naming convention. ## Checklist - [x] Tests pass - [x] Docs updated Reviewed-on: #22 Co-authored-by: M.V.
