pub fn nonzero_size_of<T>() -> uint
Returns the size of a type, or 1 if the actual size is zero.
Useful for building structures containing variable-length arrays.
Prefix searches with a type followed by a colon (e.g.
fn:) to restrict the search to a given type.
Accepted types are: fn, mod,
struct (or str), enum,
trait, typedef (or
tdef).
