pub struct ImageViewMut<'a, T, const CHANNELS: usize> { /* private fields */ }Expand description
A mutable, zero-copy interleaved image view with an explicit row stride.
Implementations§
Source§impl<'a, T, const CHANNELS: usize> ImageViewMut<'a, T, CHANNELS>
impl<'a, T, const CHANNELS: usize> ImageViewMut<'a, T, CHANNELS>
Sourcepub fn new(
width: usize,
height: usize,
row_stride: usize,
data: &'a mut [T],
) -> Result<Self, ImageError>
pub fn new( width: usize, height: usize, row_stride: usize, data: &'a mut [T], ) -> Result<Self, ImageError>
Creates a mutable view over interleaved storage.
Sourcepub fn new_with_metadata(
width: usize,
height: usize,
row_stride: usize,
data: &'a mut [T],
metadata: ImageMetadata,
) -> Result<Self, ImageError>
pub fn new_with_metadata( width: usize, height: usize, row_stride: usize, data: &'a mut [T], metadata: ImageMetadata, ) -> Result<Self, ImageError>
Creates a mutable view with validated semantic metadata.
Sourcepub const fn row_stride(&self) -> usize
pub const fn row_stride(&self) -> usize
Returns row stride in scalar elements.
Sourcepub const fn metadata(&self) -> ImageMetadata
pub const fn metadata(&self) -> ImageMetadata
Returns semantic image metadata.
Sourcepub fn set_metadata(
&mut self,
metadata: ImageMetadata,
) -> Result<(), ImageError>
pub fn set_metadata( &mut self, metadata: ImageMetadata, ) -> Result<(), ImageError>
Replaces semantic metadata after validating the channel count.
Sourcepub fn get(&self, x: usize, y: usize) -> Option<&[T; CHANNELS]>
pub fn get(&self, x: usize, y: usize) -> Option<&[T; CHANNELS]>
Returns one read-only pixel, or None outside image bounds.
Sourcepub fn get_mut(&mut self, x: usize, y: usize) -> Option<&mut [T; CHANNELS]>
pub fn get_mut(&mut self, x: usize, y: usize) -> Option<&mut [T; CHANNELS]>
Returns one mutable pixel, or None outside image bounds.
Sourcepub fn row_mut(&mut self, y: usize) -> Option<&mut [T]>
pub fn row_mut(&mut self, y: usize) -> Option<&mut [T]>
Returns a mutable packed row without trailing padding.
Sourcepub fn as_mut_slice(&mut self) -> &mut [T]
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.
Sourcepub fn subview(
&mut self,
region: ImageRegion,
) -> Result<ImageViewMut<'_, T, CHANNELS>, ImageError>
pub fn subview( &mut self, region: ImageRegion, ) -> Result<ImageViewMut<'_, T, CHANNELS>, ImageError>
Creates a checked mutable zero-copy subview.
