Newer rustc versions warn on elided named lifetimes. In thise case, it actually revealed a misleading function signature. The function defined &self with 'a. But there is no dependency on the Request reference that extends longer than this function call. Yet, the code expresses such a dependency and abuses it to force the buffer argument to match &self lifetime (and thus the return lifetime too!). Instead we want to explicitly break up the tie to the &self and tie it to the buffer instead. The 'a on &self caused a 'a on the return. With that being removed we would get an automatic '0. So we are now forced to add the 'a on the return that also fixes the compiler warning.
