sgrif/derive_deref

Adds `#[derive(Deref)]` and `#[derive(DerefMut)]`

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"));
