Crate str_macro

Creates a String with the given contents.

str! allows you to conveniently create owned Strings, similar to the vec! macro found in the Rust stdlib.

• Create an empty String

// Vec equivalent
let v = vec![];
assert_eq!(v, Vec::new());
assert!(v.is_empty());

// String
let s = str!();
assert_eq!(s, String::new());
assert!(s.is_empty());

• Create an owned String from a constant str reference.

// Vec equivalent
let v = vec!["alpha", "beta", "gamma"];
assert_eq!(&v, &["alpha", "beta", "gamma"]);
assert_eq!(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.

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

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