//! Static assert.
/// Assert a condition at compile-time.

/// See [RFC 2790] for potential addition into Rust itself.
///
/// [RFC 2790]: https://github.com/rust-lang/rfcs/issues/2790

/// # Examples
///
/// ```
/// use seer::utils::static_assert;
///
/// static_assert!(42 > 0);
/// ```
#[macro_export]

}
// I want it namespaced, even though it is exported to the root of the crate by `#[macro_export]`.
