This library provide a safe way to box FnOnce types. It doesn't use any unstable features and is therefore fully compatible with rust stable.

This library is provided because Box<FnOnce()> doesn't work yet, and Box<FnBox()> will never be available in rust stable.

The documentation for master is located at https://stbuehler.github.io/rustdocs/boxfnonce/boxfnonce/; released versions are documented at https://docs.rs/boxfnonce.
