Derive-Wrapper

A custom derive macro helper that let's you easily derive traits for wrapper types.

Examples:

#[derive(Debug, Default, Index, AsRef, LowerHexIter)]
struct Array32([u8; 32]);

#[derive(Debug, Default, LowerHex)]
struct Flag(i32);

#[derive(Debug, Index, LowerHexIter)]
struct Hi {
    #[wrap]
    a: [u8; 32],
    b: Flag,
}

#[derive(Debug, Display, From)]
#[display_from(Debug)]
struct Printer<T: std::fmt::Debug>(T);

#[derive(Default, LowerHex, Display)]
#[display_from(LowerHex)]
#[wrap = "two"]
struct Big {
    one: Array32,
    two: Hi,
}
