//! When too many lifetime requirements are added to async fns in traits, the
//! compiler may get confused, triggering this issue:
//! <https://github.com/rust-lang/rust/issues/100013>
//! This test ensures that the Rust compiler is able to prove that the
//! `CryptographicSuite::sign` returns a future that is `Send` without
//! triggering the issue.
