How do I match a String in a struct with a constant value?

Question

Is it possible to match against a String in a struct in Rust with a static str value? Here is a minimal example:

struct SomeStruct

It is not currently possible to do this in a single pattern, though at some time it is likely to become possible. For now, it’s probably easiest to replace the pattern with a pattern and match guard, like this:

match s {
    SomeStruct { ref a } if a == "Test" => {
        println!("Match");
    }
}
