Enum gdk4::SubpixelLayout

#[non_exhaustive]
pub enum SubpixelLayout {
    Unknown,
    None,
    HorizontalRgb,
    HorizontalBgr,
    VerticalRgb,
    VerticalBgr,
}

This enumeration describes how the red, green and blue components of physical pixels on an output device are laid out.

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.

Unknown

The layout is not known

None

Not organized in this way

HorizontalRgb

The layout is horizontal, the order is RGB

HorizontalBgr

The layout is horizontal, the order is BGR

VerticalRgb

The layout is vertical, the order is RGB

VerticalBgr

The layout is vertical, the order is BGR

impl Ord for SubpixelLayout

fn cmp(&self, other: &SubpixelLayout) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl PartialEq for SubpixelLayout

fn eq(&self, other: &SubpixelLayout) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
