Type size "skeleton", i.e. the only information determining a type's size.
While this is conservative, (aside from constant sizes, only pointers,
newtypes thereof and null pointer optimized enums are allowed), it is
enough to statically check common usecases of transmute.

If true, this pointer is never null.

tail: Ty<'tcx> | 🔬 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 type which determines the unsized metadata, if any,
of this pointer. Either a type parameter or a projection
depending on one, with regions erased.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
