[−][src]Macro format_xml::join

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

Displays the arguments joined with the given separator.

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

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

Optionally, the formatting can be specified:

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