error: hiding a lifetime that's elided elsewhere is confusing

   = help: the same lifetime is referred to in inconsistent ways, making the signature confusing
   = note: `-D mismatched-lifetime-syntaxes` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(mismatched_lifetime_syntaxes)]`
help: use `'_` for type paths
