This follows through on the comments on the __TestExhaustive variants
promising that their purpose will be substituted with a deny(reachable)
rustc lint once one is available.
That lint is now landing as non_exhaustive_omitted_patterns in Rust 1.57.
The correct way to use it for checking exhaustivity of a match is:
match expr {
Expr::Array(e) => {...}
Expr::Assign(e) => {...}
...
Expr::Yield(e) => {...}
#[cfg_attr(test, deny(non_exhaustive_omitted_patterns))]
_ => { /* some sane fallback */ }
}
