-# `member_constraints`
-
-The tracking issue for this feature is: [#61997]
-
-[#61997]: https://github.com/rust-lang/rust/issues/61997
-
-------------------------
-
-The `member_constraints` feature gate lets you use `impl Trait` syntax with
-multiple unrelated lifetime parameters.
-
-A simple example is:
-
-```rust
-#![feature(member_constraints)]
-
-trait Trait<'a, 'b> { }
-impl<T> Trait<'_, '_> for T {}
-
-fn foo<'a, 'b>(x: &'a u32, y: &'b u32) -> impl Trait<'a, 'b> {
-  (x, y)
-}
-
-fn main() { }
-```
-
-Without the `member_constraints` feature gate, the above example is an
-error because both `'a` and `'b` appear in the impl Trait bounds, but
-neither outlives the other.
