Rust fails to infer types for this function

Playground that works

As far I know, this should be a bug. There is only one impl of From<A> that satisfies the type constraints defined in the function, which is impl From<A> for AMain. Same thing with From<B> and impl From<B> for BMain.

edit: GitHub automatially opens the url with an extra slash, please remove it for the playground to load properly
