Lib.rs

Derives a quicker PartialOrd for types that already implement Ord.

// Input
#[derive(PartialEq, Eq, Ord, impartial_ord::ImpartialOrd)]
struct MyStruct;

// Output
impl PartialOrd for MyStruct {
    #[inline]
    fn partial_cmp(&self, other: &Self) -> Option<Ordering> {
        Some(Ord::cmp(self, other))
    }
}

lib.rs:

#
// Input
#[derive(PartialEq, Eq, Ord, impartial_ord::ImpartialOrd)]
struct MyStruct { foo: Bar, qux: Baz, }

// Output
impl PartialOrd for MyStruct where Self: Ord {
  #[inline]
  fn partial_cmp(&self, other: &Self) -> Option<Ordering> {
    Some(Ord::cmp(self, other))
  }
