Provided Associated Constants§

Source

const NONE_COLOR: Rgb888 = _

Color used to display None values when EG_FANCY_PANIC is enabled.

This color must be set to a color that isn’t available in normal patterns to make it distinguishable in the output. For non grayscale colors the default value should be used.

Required Methods§

Source

fn char_to_color(c: char) -> Self

Converts a char into a color of type C.

Source

fn color_to_char(color: Self) -> char

Converts a color of type C into a char.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
