Enum SubpixelOrder

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

Some output devices (such as LCD panels) display colors by making each pixel consist of smaller “subpixels” that each have a particular color. By using knowledge of the layout of this subpixel components, it is possible to create image content with higher resolution than the pixel grid.

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 of subpixel components for the device is unknown.

None

the device displays colors without geometrically-separated subpixel components, or the positioning or colors of the components do not match any of the values in the enumeration.

HorizontalRgb

the device has horizontally arranged components in the order red-green-blue from left to right.

HorizontalBgr

the device has horizontally arranged components in the order blue-green-red from left to right.

VerticalRgb

the device has vertically arranged components in the order red-green-blue from top to bottom.

VerticalBgr

the device has vertically arranged components in the order blue-green-red from top to bottom.

Trait Implementations

impl Clone for SubpixelOrder

fn clone(&self) -> SubpixelOrder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SubpixelOrder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SubpixelOrder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SubpixelOrder

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SubpixelOrder

fn cmp(&self, other: &SubpixelOrder) -> 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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SubpixelOrder

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SubpixelOrder

fn partial_cmp(&self, other: &SubpixelOrder) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
