Struct ImageViewMut 

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

A mutable, zero-copy interleaved image view with an explicit row stride.

Implementations

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

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

Creates a mutable view over interleaved storage.

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

Creates a mutable 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 metadata(&self) -> ImageMetadata

Returns semantic image metadata.

pub fn set_metadata( &mut self, metadata: ImageMetadata, ) -> Result<(), ImageError>

Replaces semantic metadata after validating the channel count.

pub fn as_view(&self) -> ImageView<'_, T, CHANNELS>

Reborrows this mutable view as read-only.

pub fn get(&self, x: usize, y: usize) -> Option<&[T; CHANNELS]>

Returns one read-only pixel, or None outside image bounds.

pub fn get_mut(&mut self, x: usize, y: usize) -> Option<&mut [T; CHANNELS]>

Returns one mutable pixel, or None outside image bounds.

pub fn row_mut(&mut self, y: usize) -> Option<&mut [T]>

Returns a mutable packed row without trailing padding.

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

Returns the complete mutable backing span, including inter-row padding.

The final row has no required trailing padding, so the returned length is the minimum checked span accepted by ImageViewMut::new.

pub fn subview( &mut self, region: ImageRegion, ) -> Result<ImageViewMut<'_, T, CHANNELS>, ImageError>

Creates a checked mutable zero-copy subview.

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

Formats the value using the given formatter.
