740: Fix two nightly errors r=Kerollmops a=irevoire

Currently, we have these two errors on rust nightly. It would be nice to help rustc understand what's going on

```
error[E0658]: anonymous lifetimes in `impl Trait` are unstable
   --> filter-parser/src/lib.rs:173:53

    |
    = help: add `#![feature(anonymous_lifetime_in_impl_trait)]` to the crate attributes to enable
