-/// A type specification.
-///
-/// This contains the actual type as well as an optional compile-time
-/// known displayed representation of the type. This is useful for cases
-/// where the type is used through a type alias in order to provide
-/// information about the alias name.
-///
-/// # Examples
-///
-/// Consider the following Rust function:
-/// ```no_compile
-/// fn is_sorted(input: &[i32], pred: Predicate) -> bool;
-/// ```
-/// In this above example `input` would have no displayable name,
-/// `pred`'s display name is `Predicate` and the display name of
-/// the return type is simply `bool`. Note that `Predicate` could
-/// simply be a type alias to `fn(i32, i32) -> Ordering`.
