asserttokenseq

Like Rust's built-in assert_eq macro, but for token streams. Passes them through rustfmt, and shows a pretty diff (powered by [pretty_assertions]).

How it works

You write:

rust let got = something_that_generates_rust_code(); let expected = quote! { #[no_mangle] extern "C" fn foo( input: *const ::libc::c_char, input_len: ::libc::size_t, input3: *const ::libc::c_int, input3_len: ::libc::size_t, ) { fn foo(input: Arc<str>, input2: Arc<str>) {} unimplemented!() } }; assert_tokens_eq!(got, expected);

and you get:
