Merge #740
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 | 173 | fn ws<'a, O>(inner: impl FnMut(Span<'a>) -> IResult<O>) -> impl FnMut(Span<'a>) -> IResult<O> { | ^ expected named lifetime parameter | = help: add `#![feature(anonymous_lifetime_in_impl_trait)]` to the crate attributes to enable help: consider introducing a named lifetime parameter | 173 | fn ws<'a, 'a, O>(inner: impl FnMut(Span<'a>) -> IResult<'a, O>) -> impl FnMut(Span<'a>) -> IResult<O> { | +++ +++ error[E0658]: anonymous lifetimes in `impl Trait` are unstable --> filter-parser/src/error.rs:36:49 | 36 | mut parser: impl FnMut(Span<'a>) -> IResult<O>, | ^ expected named lifetime parameter | = help: add `#![feature(anonymous_lifetime_in_impl_trait)]` to the crate attributes to enable help: consider introducing a named lifetime parameter | 35 ~ pub fn cut_with_err<'a, 'a, O>( 36 ~ mut parser: impl FnMut(Span<'a>) -> IResult<'a, O>, | For more information about this error, try `rustc --explain E0658`. error: could not compile `filter-parser` due to 2 previous errors ``` Co-authored-by: Tamo <tamo@meilisearch.com>
