Struct TileBuf 

pub struct TileBuf { /* private fields */ }

An owned, densely packed buffer of pixels for one region.

This is what the M1 evaluator materializes per node. It is deliberately simple: M2 replaces most uses with scheduler-owned tile memory, but the buffer’s view API (TileBuf::as_tile, TileBuf::as_tile_mut) is the same one kernels already program against, so kernels do not change.

Implementations

impl TileBuf

pub fn zeroed(region: Region, pixel: PixelFormat) -> Result<Self>

Allocate a zeroed, densely packed buffer covering region.

Errors

Returns PixelsError::InvalidArgument if the region’s byte length overflows usize on this platform.

pub fn for_image(desc: &ImageDescriptor) -> Result<Self>

Allocate a zeroed buffer covering the whole of desc.

Errors

As TileBuf::zeroed.

pub fn from_vec( region: Region, pixel: PixelFormat, data: Vec<u8>, ) -> Result<Self>

Take ownership of data as the pixels of region, densely packed.

Errors

Returns PixelsError::InvalidArgument if data is not exactly the packed byte length of region.

pub const fn region(&self) -> Region

The region this buffer covers.

pub const fn pixel(&self) -> PixelFormat

The pixel format of the samples in this buffer.

pub fn bytes(&self) -> &[u8]

The packed bytes of this buffer.

pub fn into_bytes(self) -> Vec<u8>

Consume the buffer, returning its packed bytes.

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

Borrow the buffer as an immutable tile.

Errors

Only if the buffer’s own invariants were violated, which construction prevents.

pub fn as_tile_mut(&mut self) -> Result<TileMut<'_>>

Borrow the buffer as a mutable tile.

Errors

As TileBuf::as_tile.
