this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

The TypeFoldable trait is implemented for every type that can be folded. Basically, every type that has a corresponding method in TypeFolder.

To implement this conveniently, use the BraceStructTypeFoldableImpl etc macros found in macros.rs.
