Expand description

Helper macro for creating a wrapper type.

The wrapper type will implement Deref, DerefMut, From and AsRef.

ยงExample

wrapper!(pub MyString(String));
// Derive is OK!
wrapper!(pub MyStringDerived(String), derive(Debug, Clone, PartialEq, Eq, Hash));
// Lifetime is supported too!
wrapper!(pub MyStringLifetime<'a>(&'a str));
wrapper!(pub MyStringLifetimePubDerived<'a>(pub &'a str), derive(Debug, Clone, PartialEq, Eq, Hash));
