Struct Gray4

pub struct Gray4(/* private fields */);

4 bit grayscale color.

Implementations

impl Gray4

pub const fn new(luma: u8) -> Self

Creates a new grayscale color.

Too large luma values are masked to the valid range by setting the upper bits to 0.

Converts to this type from the input type.

impl From<Gray4> for Rgb555

fn from(other: Gray4) -> Self

Converts to this type from the input type.

impl From<Gray4> for Rgb565

fn from(other: Gray4) -> Self

Converts to this type from the input type.

impl From<Gray4> for Rgb888

fn from(other: Gray4) -> Self

Converts to this type from the input type.

impl From<RawU4> for Gray4

fn from(data: RawU4) -> Self

Converts to this type from the input type.

impl GrayColor for Gray4

const BLACK: Self = _

Black color (0% luma)

const WHITE: Self = _

White color (100% luma)

fn luma(&self) -> u8

Returns the luma channel value.

impl Hash for Gray4

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 Gray4

fn cmp(&self, other: &Gray4) -> 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 Gray4

fn eq(&self, other: &Gray4) -> 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 Gray4

fn partial_cmp(&self, other: &Gray4) -> 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.

impl PixelColor for Gray4

type Raw = RawU4

Raw data type.

impl Copy for Gray4

impl Eq for Gray4

impl StructuralPartialEq for Gray4

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
