Traits and impls in Rust are based on type classes, which originated
in Haskell. You may find it interesting to read about type classes:

(Interfaces have been renamed to traits in the soon-to-be-released
Rust 0.4 release, by the way; it looks like you may be looking at the docs
from Rust 0.3.)

Multiple parameter are very useful eg a collection and a second type ,
but it gets messy... it works ok provided its in a single compilation unit
but else you get compilation unit dependency loops ,with generics ( which
are similar) you can auto generate new libs to handle this not sure about
