It's not obvious how to use different colors in if-else

[kriomant]

I tried to print different words with different colours depending on condition:

println!("operation is {}",
    if op.success {
        "successful".bright_green()
    } else {
        "failed".bright_red()
    }
);

This doesn't work because color is encoded into type of returned wrapper.

I've managed to solve it using:

println!("operation is {}",
    if op.success {
        "successful".color(AnsiColors::BrightGreen)
    } else {
        "failed".color(AnsiColors::BrightRed)
    }
);

But it would be cool to be able to perform such conversion more conveniently, so you don't have to rewrite code that much (function name may be arbitrary):

println!("operation is {}",
    if op.success {
        "successful".bright_green().downgrade() // converts statically-known color to common type which stores color as value
    } else {
        "failed".bright_red().downgrade()
    }
);
