Struct SharedSubgrid

pub struct SharedSubgrid<'g, V = f32> { /* private fields */ }

Implementations

impl<'g, V> SharedSubgrid<'g, V>

pub unsafe fn new( ptr: NonNull<V>, width: usize, height: usize, stride: usize, ) -> Self

Create a SharedSubgrid from raw pointer to the buffer, width, height and stride.

Safety

The memory region specified by width, height and stride must be valid.

pub fn from_buf( buf: &'g [V], width: usize, height: usize, stride: usize, ) -> Self

Create a SharedSubgrid from buffer slice, width, height and stride.

Panic

Panics if:

• either width or height is zero,
• width is greater than stride,
• or the area specified by width, height and stride is larger than buf.

pub fn width(&self) -> usize

pub fn height(&self) -> usize

pub fn get(&self, x: usize, y: usize) -> &V

pub fn get_row(&self, row: usize) -> &[V]

impl<'g, V> SharedSubgrid<'g, V>

pub fn split_horizontal( &self, x: usize, ) -> (SharedSubgrid<'g, V>, SharedSubgrid<'g, V>)

Split the grid horizontally at an index.

Panics

Panics if x > self.width().

pub fn split_vertical( &self, y: usize, ) -> (SharedSubgrid<'g, V>, SharedSubgrid<'g, V>)

Split the grid vertically at an index.

Panics

Panics if y > self.height().

pub fn subgrid( &self, range_x: impl RangeBounds<usize>, range_y: impl RangeBounds<usize>, ) -> SharedSubgrid<'g, V>

impl<'g> SharedSubgrid<'g, f32>

pub fn as_vectored<V: SimdVector>(&self) -> Option<SharedSubgrid<'g, V>>

pub unsafe fn as_atomic_i32(&self) -> SharedSubgrid<'g, AtomicI32>

Safety

Caller should make sure that atomic and non-atomic accesses are not mixed.
