Java would be “test string”.toString(). C# has “test string”.ToString(). Python has str(“test string”) (as str() is Python’s toString equivalent). Rust has String::from(“test string”).to_string().
That’s just from the top of my head. I’m sure there’s more.
Edit: actually, I think Rust’s to_string() may not be entirely useless, I think it may be used as a consuming placeholder for clone()? Not sure how that would be useful, but it’s not a complete no-op at least.
