s-macro

A basic Rust library for conveniently making a String. Like so:

```rust use s_macro::s;

assert!(s!() == String::new()); assert!(s!("hello, world") == String::from("hello, world")); assert!(s!(123 + 321) == format!("{}", 123 + 321));

let world = "world"; assert!(s!("hello, {}", world) == format!("hello, {}", world)); assert!(s!("hello, {world}") == format!("hello, {world}")); ```
