Bug on latest nightly: does not have a "def_span"

[serzhiio]

The part of ExchangeCommonTrait:

pub trait ExchangeCommonTrait<IntercomMain: Debug, IntercomSelf: Debug> {
    type LoopContext;
    type LoopEvent<'a>;
    ...
}

And backtrace:

   Compiling dummy_exchange v0.1.0 (/home/serzh-dev/dev/apps/@exchanges/dummy_exchange)
