//! Workarounds for Rust 1.63 where some things in the `static_assertions`
//! crate do things that don't work in const contexts. We want to call them in
//! const contexts in Rust versions where that's supported so that problems are
//! caught at compile time, and fall back to dynamic asserts in Rust 1.63.
