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?

Identifies a particular impl in the source, along with a set of substitutions from the impl's type/lifetime parameters. The nested vector corresponds to the nested obligations attached to the impl's type parameters.

The type parameter N indicates the type used for "nested obligations" that are required by the impl. During type check, this is Obligation, as one might expect. During trans, however, this is (), because trans only requires a shallow resolution of an impl, and nested obligations are satisfied later.
