JFC. When will open source projects like @rustlang learn that putting toxic people like this in positions of ANY authority is unacceptable. https://github.com/marshallpierce/rust-base64/issues/213 . He's showing you who he is, and you're not listening.
That particular interaction was handled poorly, but isn't this issue about adding essentially two 3 line helper functions to the library? Forking just for that seems unnecessary. You can instead make a new library that depends on this one and which defines your helper functions, or just copy the helpers into each project you use. It would be more convenient in
base64, but it's not like it's the end of the world either.
