str-macro

Rust crate for the str!() macro, which makes the conveniences available from vec![] available for String as well.

Has no dependencies, and should work on any Rust release channel.

• Create an empty String

```rust // Vec equivalent let v = vec![]; asserteq!(v, Vec::new()); assert!(v.isempty());

// String let s = str!(); asserteq!(s, String::new()); assert!(s.isempty()); ```

• Create an owned String from a constant str reference.

```rust // Vec equivalent let v = vec!["alpha", "beta", "gamma"]; asserteq!(&v, &["alpha", "beta", "gamma"]; asserteq!(v.len(), 3);

// String let s = str!("alpha beta gamma"); assert_eq!(&s, "alpha beta gamma"); let _: String = s; ```

• Create an owned String from an object which implements ToString.

Note that this is automatically implemented for anything that implements Display.

```rust let s = str!(2194); assert_eq!(&s, "2194");

let s = str!(Ipv4Addr::new(127, 0, 0, 1)); assert_eq!(&s, "127.0.0.1"); ```
