Trait Implementations

impl<T> AsMut<T> for Gray<T>[+]

[+] Show hidden undocumented items

fn as_mut(&mut self) -> &mut T[−]

Performs the conversion.

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

[+] Show hidden undocumented items

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> AsRef<T> for Gray<T>[+]

[+] Show hidden undocumented items

fn as_ref(&self) -> &T[−]

Performs the conversion.

impl<ComponentType: Clone> Clone for Gray<ComponentType>[+]

[+] Show hidden undocumented items

fn clone(&self) -> Gray<ComponentType>[−]

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl<T> ComponentSlice<T> for Gray<T>[+]

[+] Show hidden undocumented items

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<ComponentType: Copy> Copy for Gray<ComponentType>

Formats the value using the given formatter.

impl<ComponentType: Default> Default for Gray<ComponentType>[+]

[+] Show hidden undocumented items

fn default() -> Gray<ComponentType>[−]

Returns the “default value” for a type.
