Module wrapper 

Wrapper are how dbstruct reads and writes to the database. They handle serializing and deserializing, provide the API and determine how to handle missing data.

There are two types of wrapper:

• Those describing how to handle missing values. These at the minimum offer you get and set. Depending on the traits the database you chose implements they may also support update and conditional_update.
• Wrapper that mimic the API of a standard library type.

Structs

DefaultTrait

Map

mimics the API of HashMap

OptionValue
