Struct TileMut 

pub struct TileMut<'a> { /* private fields */ }

A mutable strided view over a region of pixels.

This is the output half of Op::compute: the evaluator hands the kernel a TileMut sized to the region it must fill.

Implementations

impl<'a> TileMut<'a>

pub fn new( region: Region, pixel: PixelFormat, stride: usize, data: &'a mut [u8], ) -> Result<Self>

Wrap data as a mutable tile covering region.

Errors

As Tile::new.

pub const fn region(&self) -> Region

The region of the image this tile covers.

pub const fn pixel(&self) -> PixelFormat

The pixel format of the samples in this tile.

pub const fn stride(&self) -> usize

Distance in bytes between the starts of consecutive rows.

pub const fn row_bytes(&self) -> usize

Packed length in bytes of one row of this tile.

pub fn row_mut(&mut self, y: u32) -> Option<&mut [u8]>

The row at image coordinate y, or None if outside the region.

pub fn rows_mut(&mut self) -> impl Iterator<Item = &mut [u8]>

The tile’s rows, top to bottom, mutably.

pub fn as_ref(&self) -> Tile<'_>

Reborrow as an immutable tile.

Trait Implementations

impl<'a> Debug for TileMut<'a>

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

Formats the value using the given formatter.
