Struct cssparser::CowRcStr

pub struct CowRcStr<'a> { /* fields omitted */ }

A string that is either shared (heap-allocated and reference-counted) or borrowed.

Equivalent to enum { Borrowed(&'a str), Shared(Rc<String>) }, but stored more compactly.

FIXME(https://github.com/rust-lang/rfcs/issues/1230): use an actual enum if/when the compiler can do this layout optimization.
