A simple macro that auto insert .to_string() call to str literal.
It can save many keystrokes while writing test.
rust
s!{
MyStruct {
a: "a",
b: "b",
c: 1,
}
}
will expand to
rust
MyStruct {
a: "a".to_string(),
b: "b".to_string(),
c: 1,
}
Currently embed macro won't work, so you can't use s!{vec!["a","b","c"]}
