What are the present implementations of strings and arrays in Rust? And

struct RustString {

typedef *RustString ~str;
(If `~` were a valid identifier character in C, that is.) ;)
But Daniel did some performance measurements and found that this had
suboptimal performance characteristics when compared to:
struct ~str {
char *ptr;
int size;
int cap;
}
So we're changing to the latter.
By the way, I agree with Daniel that in an ideal world none of this
would be baked into the compiler (except syntactically), and I would
like to take steps to move to that world post Rust 1.0. However, given
that we have dynamically sized types and as a result we have to define
`~str` to mean *something*, we have to build in some representation into
the compiler.
