//! Compile-fail tests.
//!
//! `matches_struct!` without a trailing `..` expands to a struct pattern that
//! lists exactly the named fields, so a missing or unknown field is a hard
//! error from the destructure. A misplaced `..` is caught by the macro itself.
//!
//! The async `expect!` case locks that the sync `to` cannot be pointed at a
//! future with an output matcher: that path must go through `resolves_to`.
