Trait Implementations

impl<T> AsPixels<Gray<T>> for [T]

fn as_pixels(&self) -> &[Gray<T>]

Reinterpret the slice as a read-only/shared slice of pixels. Multiple consecutive elements in the slice are intepreted as a single pixel (depending on format, e.g. 3 for RGB, 4 for RGBA).

fn as_pixels_mut(&mut self) -> &mut [Gray<T>]

Reinterpret the slice as a mutable/exclusive slice of pixels. Multiple consecutive elements in the slice are intepreted as a single pixel (depending on format, e.g. 3 for RGB, 4 for RGBA).

impl<T> ComponentSlice<T> for Gray<T>

fn as_slice(&self) -> &[T]

The components interpreted as an array, e.g. one RGB expands to 3 elements.

fn as_mut_slice(&mut self) -> &mut [T]

impl<T> Deref for Gray<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<ComponentType: PartialEq> PartialEq<Gray<ComponentType>> for Gray<ComponentType>

fn cmp(&self, other: &Gray<ComponentType>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl<ComponentType: PartialOrd> PartialOrd<Gray<ComponentType>> for Gray<ComponentType>

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

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

fn lt(&self, other: &Gray<ComponentType>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Gray<ComponentType>) -> bool

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

fn gt(&self, other: &Gray<ComponentType>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Gray<ComponentType>) -> bool

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