Macro error 

macro_rules! error {
    ($format_str:literal $(, $arg:expr)* $(,)?) => { ... };
    ([$($format_str:literal),+ $(,)?] $(, $arg:expr)* $(,)?) => { ... };
}

Like log::error, but bunt-compatible.

Example

use bunt_logger::error;

let x = -1;
error!("{$red}Not a positive number:{/$} {[bold]}", x);
