Struct ImageView 

pub struct ImageView<'a, T, const CHANNELS: usize> { /* private fields */ }

A read-only, zero-copy image view with an explicit row stride.

Implementations

impl<'a, T, const CHANNELS: usize> ImageView<'a, T, CHANNELS>

pub fn new( width: usize, height: usize, row_stride: usize, data: &'a [T], ) -> Result<Self, ImageError>

Creates a view over interleaved storage.

row_stride is measured in scalar elements, not bytes.

pub fn new_with_metadata( width: usize, height: usize, row_stride: usize, data: &'a [T], metadata: ImageMetadata, ) -> Result<Self, ImageError>

Creates a view with validated semantic metadata.

pub const fn width(self) -> usize

Returns image width in pixels.

pub const fn height(self) -> usize

Returns image height in pixels.

pub const fn row_stride(self) -> usize

Returns row stride in scalar elements.

pub const fn layout(self) -> ImageLayout

Returns physical channel layout.

pub const fn metadata(self) -> ImageMetadata

Returns semantic image metadata.

pub fn get(self, x: usize, y: usize) -> Option<&'a [T; CHANNELS]>

Returns one pixel, or None outside image bounds.

pub fn row(self, y: usize) -> Option<&'a [T]>

Returns a packed row without its trailing padding.

pub fn subview(self, region: ImageRegion) -> Result<Self, ImageError>

Creates a checked zero-copy subview.

Trait Implementations

impl<'a, T: Clone, const CHANNELS: usize> Clone for ImageView<'a, T, CHANNELS>

fn clone(&self) -> ImageView<'a, T, CHANNELS>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug, const CHANNELS: usize> Debug for ImageView<'a, T, CHANNELS>

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

Formats the value using the given formatter.

impl<'a, T: Copy, const CHANNELS: usize> Copy for ImageView<'a, T, CHANNELS>
