Trait Sample 

pub trait Sample<'a, Space: CoordinateSpace> {
    type Output: 'a;

    // Required method
    fn sample(
        &mut self,
        rect: &Rectangle<Space>,
    ) -> impl Iterator<Item = (Coordinates<Space>, &'a mut Self::Output)>;
}

Types that can provide direct hardware access to individual pixels within a given Virtual rectangle shaped selection for reading and writing

Required Associated Types

type Output: 'a

The type of pixel this sampler supports

Required Methods

fn sample( &mut self, rect: &Rectangle<Space>, ) -> impl Iterator<Item = (Coordinates<Space>, &'a mut Self::Output)>

Provides a [PixelView] over the given Rectangle selection

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<'a, Pixel: 'a> Sample<'a, LinearSpace> for [Pixel]

type Output = Pixel

fn sample( &mut self, rect: &Rectangle<LinearSpace>, ) -> impl Iterator<Item = (Coordinates<LinearSpace>, &'a mut Self::Output)>

impl<'a, Pixel: 'a, const N: usize> Sample<'a, LinearSpace> for [Pixel; N]

type Output = Pixel

fn sample( &mut self, rect: &Rectangle<LinearSpace>, ) -> impl Iterator<Item = (Coordinates<LinearSpace>, &'a mut Self::Output)>
