Macro kompact::let_irrefutable

macro_rules! let_irrefutable {
    ($name:ident, $pattern:pat = $expression:expr) => { ... };
}

A macro that provides a shorthand for an irrefutable let binding, that the compiler cannot determine on its own

This is equivalent to the following code: let name = if let Pattern(name) = expression { name } else { unreachable!(); };
