Having a 'static lifetime requirement on Handlers seriously cripples handlers. This means you cannot have any &Ts in Handlers that aren't static also. I encountered this problem today while trying to integrate ivanceras/rustorm today with rustful with this code snippet. This doesn't work because ApiHandler stores a &Database, which isn't 'static. I work around this issue by diving a bit lower and passing around the r2d2 connection pool instead, but that heavily bloats my code.

tl;dr: please make Handler not require 'static, it would make it a lot more flexible
