Macro format_xml::spaced

macro_rules! spaced {
    ($($e:expr),+) => { ... };
    ($($e:expr),+; $s:literal) => { ... };
}

Displays the arguments as space-separated values.

The arguments are moved instead of captured by reference unlike format_args!.

let result = spaced!(1, 2.0, true).to_string();
assert_eq!(result, "1 2 true");

Optionally, the formatting can be specified:

let result = spaced!(10, 11, 12; "{:#x}").to_string();
assert_eq!(result, "0xa 0xb 0xc");
