Creates a formatted string. Analogous to format!.

See the crate root for general help on the syntax.

This macro returns String containing the formatted text.

Panics

The macro will panic if formatting fails (which shoudn't happen for any of std types).

Examples

let v = [1, 2];

let s = fomat!("Hello, "[v]);
assert_eq!(s, "Hello, [1, 2]");

let s = fomat!(for x in &v { (x*x) ";" });
assert_eq!(s, "1;4;");
