(synopsis "Adds derive macros for more traits")
(description
"Rust has lots of builtin traits that are implemented for its basic
types, such as @code{Add}, @code{Not}, @code{From} or @code{Display}.
However, when wrapping these types inside your own structs or enums you lose
the implementations of these traits and are required to recreate them. This is
especially annoying when your own structures are very simple, such as when
using the commonly advised newtype pattern (e.g. @code{MyInt(i32)}).
This library tries to remove these annoyances and the corresponding
boilerplate code. It does this by allowing you to derive lots of commonly used
traits for both structs and enums.")
