-//! This module implements manually tracked test coverage, which useful for
-//! quickly finding a test responsible for testing a particular bit of code.
-//!
-//! See https://matklad.github.io/2018/06/18/a-trick-for-test-maintenance.html
-//! for details, but the TL;DR is that you write your test as
-//!
-//! ```no-run
-//! #[test]
-//! fn test_foo() {
-//!     covers!(test_foo);
-//! }
-//! ```
-//!
-//! and in the code under test you write
-//!
-//! ```no-run
-//! fn foo() {
-//!     if some_condition() {
-//!         tested_by!(test_foo);
-//!     }
-//! }
-//! ```
-//!
-//! This module then checks that executing the test indeed covers the specified
-//! function. This is useful if you come back to the `foo` function ten years
-//! later and wonder where the test are: now you can grep for `test_foo`.
