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 AST represents all type param bounds as types. typeck::collect::compute_bounds matches these against the "special" built-in traits (see middle::lang_items) and detects Copy, Send and Sync.
