Enum VisualType 

#[non_exhaustive]
pub enum VisualType {
    StaticGray,
    Grayscale,
    StaticColor,
    PseudoColor,
    TrueColor,
    DirectColor,
}

A set of values that describe the manner in which the pixel values for a visual are converted into RGB values for display.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StaticGray

Each pixel value indexes a grayscale value directly.

Grayscale

Each pixel is an index into a color map that maps pixel values into grayscale values. The color map can be changed by an application.

StaticColor

Each pixel value is an index into a predefined, unmodifiable color map that maps pixel values into RGB values.

PseudoColor

Each pixel is an index into a color map that maps pixel values into rgb values. The color map can be changed by an application.

TrueColor

Each pixel value directly contains red, green, and blue components. Use Visual::red_pixel_details(), etc, to obtain information about how the components are assembled into a pixel value.

DirectColor

Each pixel value contains red, green, and blue components as for TrueColor, but the components are mapped via a color table into the final output table instead of being converted directly.
