(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.")
