Struct fern::colors::WithFgColor

source ·

pub struct WithFgColor<T>where
    T: Display,{ /* private fields */ }

Expand description

Opaque structure which represents some text data and a color to display it with.

This implements fmt::Display to displaying the inner text (usually a log level) with ANSI color markers before to set the color and after to reset the color.

WithFgColor instances can be created and displayed without any allocation.
