Short for "Database", it stores data by unique identifiers

An empty Db with no entries

Insert an item into the Db under the given Id

Insert many items into the Db under their given Ids

Insert an item into a Db without an Id. This function takes a Random.Seed because it generates a random Id for the item you are inserting into the Db. This function gaurantees no id collisions; if the id it generates already exists, it simply tries again with a different id.

Update an item in a Db, using an update function. If the item doesnt exist in the Db, it comes into the update as Nothing. If a Nothing comes out of the update function, the value under that id will be removed.

Remove the item at the given Id, if it exists

Get the item under the provided Id

Get many items from a Db from a list of Ids. Elements not in the Db simply wont appear in the return result.

Just like get, except it comes with the Id, for those cases where you dont want the item separated from its Id

Get many items from a Db, but dont filter out missing results, and pair results with their Id

Determine if a certain Id is in a Db

Turn your Db into a list

Initialize a Db from a list of id-value pairs

turn a Db item into a Dict String item

Map a Db to a different data type.

Apply a change to just one item in the Db, assuming the item is in the Db in the first place. This function is just like update except deleting the item is not possible.
