Casey

Case transforming macros

Casey transforms the case of given input idents.
Niche but maybe useful in other macros.

use casey::{pascal, lower, shouty, snake, upper};

lower!(ABC);    // renders: `abc`
upper!(abc);    // `ABC`
snake!(ABC);    // `a_b_c`
pascal!(ab_c);  // `AbC`
shouty!(a_b_c); // `A_B_C`

Token Stream

Casey macros can operate on TokenStreams e.g.

    snake!(
        struct MockStruct {}
        impl MockStruct {
            fn test() -> bool { true }
        }
    );
    assert!(mock_struct::test());

All ident tokens in the stream will have the case transformation applied.
