In the + process, several portions of code were revised to be methods on new, + custom types, rather than functions taking interchangeable types, thus + increasing type safety of the module. Custom error types and handling + were added as well, in order to facilitate better error dismissal/handling + in outside crates and avoid mistakenly passing an internal error string to + C over the FFI boundary. Many tests were added, and some previous + differences between the C and Rust implementations have been + remedied. Fixes bug 24031; bugfix on 0.3.3.1-alpha. |
