Struct canvas::Pixel

pub struct Pixel<P: ?Sized>(_);

Marker struct to denote a pixel type.

Can be constructed only for types that have expected alignment and no byte invariants. It always implements Copy and Clone, regardless of the underlying type and is zero-sized.

Methods

impl<P: AsBytes + FromBytes> Pixel<P>

pub fn for_type() -> Option<Self>

Try to construct an instance of the marker.

If successful, you can freely use it to access the image buffers.

impl<P> Pixel<P>

pub fn align(self) -> usize

Proxy of core::mem::align_of.

pub fn size(self) -> usize

Proxy of core::mem::size_of.

Trait Implementations

impl<P> Clone for Pixel<P>

This is a pure marker type.

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P> Copy for Pixel<P>

This is a pure marker type.

impl<P> Debug for Pixel<P>

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

Formats the value using the given formatter.

impl<P> Eq for Pixel<P>

impl<P> Ord for Pixel<P>

fn cmp(&self, _: &Self) -> 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<P> PartialEq<Pixel<P>> for Pixel<P>

fn eq(&self, _: &Self) -> bool

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<P> PartialOrd<Pixel<P>> for Pixel<P>

fn partial_cmp(&self, _: &Self) -> Option<Ordering>

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

#[must_use] fn lt(&self, other: &Rhs) -> bool

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

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

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

#[must_use] fn ge(&self, other: &Rhs) -> bool

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