DESCRIPTION

In DBIx::Class, a user normally receives query results as instances of a certain Result Class, depending on the main query source. Besides being the primary "toolset" for interaction with your data, a Result Class also serves to establish source metadata, which is then used during initialization of your DBIx::Class::Schema instance.

Because of these multiple seemingly conflicting purposes, it is hard to aggregate the documentation of various methods available on a typical Result Class. This document serves as a general overview of Result Class declaration best practices, and offers an index of the available methods (and the Components/Roles which provide them).
