This declares PlanReader as being parameterized by some type that
implements io::Reader, but that type has nothing to do with Self.
Also, method implementations in trait definitions are only defaults
for types that implement the trait; an impl is still required to
declare that a type implements it.
You probably want:
trait PlanReader {
fn read_9p_s(&mut self) -> io::IoResult<~str>;
}
impl<R: io::Reader> PlanReader for R {
fn read_9p_s(&mut self) -> io::IoResult<~str> { ... }
}
