error-code's Issues

`if` is not allowed in a `const fn`

I'm compiling this crate because it's a dependency of the clipboard-win crate that I'm using.

It used to work alright, but today I'm re-compiling and I get an error message:

   Compiling error-code v2.0.1
error[E0658]: `if` is not allowed in a `const fn`
   --> c:\dev-tools\Rust\.cargo\registry\src\github.com-1ecc6299db9ec823\error-code-2.0.1\src\lib.rs:141:13

    = help: add `#![feature(const_if_match)]` to the crate attributes to enable

I'm on rustc 1.45.0-nightly (f8d394e51 2020-05-05).
