🔬 This is a nightly-only experimental API. (rustc_private)

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 kind of pointer and associated metadata (thin, length or vtable) - we only allow casts between fat pointers if their metadata have the same kind.
