Remove dependency on mac crate (#639)
* Replace mac::format_if * Replace mac::test_eq * Move macros to markup5ever - Use xml5ever version of time! macro - Replace mac::unwrap_or_return with version from html5ever * Remove mac dependency Signed-off-by: Nico Burns <[email protected]> * Use ? operator instead of unwrap_or_return where possible Signed-off-by: Nico Burns <[email protected]> * Duplicate macros rather than exposing publicly Signed-off-by: Nico Burns <[email protected]> --------- Signed-off-by: Nico Burns <[email protected]>
