derive_deref
This crate adds a simple #[derive(Deref)] and #[derive(DerefMut)].
It can be used on any struct with exactly one field.
If the type of that field is a reference,
the reference will be returned directly.
Example
#[derive(Deref)]
struct MyInt(i32);
assert_eq!(&1, &*MyInt(1));
assert_eq!(&2, &*MyInt(2));
#[derive(Deref)]
struct MyString<'a>(&'a str);
// Note that we deref to &str, not &&str
assert_eq!("foo", &*MyString("foo"));
assert_eq!("bar", &*MyString("bar"));License
