Macro bunt::write

write!() { /* proc-macro */ }

Writes formatted data to a termcolor::WriteColor target.

This is a more general version of print as you can specify the destination of the formatted data as first parameter. write also returns a Result<(), std::io::Error> which is Err in case writing to the target or setting the color fails. print! simply panics in that case.

use bunt::termcolor::{ColorChoice, StandardStream};

// Printing to stderr, just to show something `print` can't do.
let mut stderr = StandardStream::stderr(ColorChoice::Auto);
let result = bunt::write!(stderr, "{$red}bad error!{/$}");

if result.is_err() {
    // Writing to stderr failed...
}
