 <span id="ut">uninhabited type</span>          &nbsp; |  A type which has _no_ values. This is not the same as a ZST, which has exactly 1 value. An example of an uninhabited type is `enum Foo {}`, which has no variants, and so, can never be created. The compiler can treat code that deals with uninhabited types as dead code, since there is no such value to be manipulated. `!` (the never type) is an uninhabited type. Uninhabited types are also called "empty types".
 <span id="upvar">upvar</span>                  &nbsp; |  A variable captured by a closure from outside the closure.
 <span id="variance">variance</span>            &nbsp; |  Determines how changes to a generic type/lifetime parameter affect subtyping; for example, if `T` is a subtype of `U`, then `Vec<T>` is a subtype `Vec<U>` because `Vec` is *covariant* in its generic parameter. See [the background chapter](./background.md#variance) for a more general explanation. See the [variance chapter](../variance.md) for an explanation of how type checking handles variance.
-<span id="variant-idx">variant index</span>    &nbsp; |  In an enum, identifies a variant by assigning them indices starting at 0.  This is purely internal and not to be confused with the ["discrimiant"](#discriminant) which can be overwritten by the user (e.g. `enum Bool { True = 42, False = 0 }`).

 <span id="zst">ZST</span>                      &nbsp; |  Zero-Sized Type. A type whose values have size 0 bytes. Since `2^0 = 1`, such types can have exactly one value. For example, `()` (unit) is a ZST. `struct Foo;` is also a ZST. The compiler can do some nice optimizations around ZSTs.

 generic types: _early-_ and _late-_ bound parameters.
 Basically, if we cannot represent a type (e.g. a universally quantified type),
 we have to bind it _early_ so that the unrepresentable type is never around.
