Struct MutableSubgrid

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

A mutable subgrid of the underlying buffer.

Implementations

impl<'g, V> MutableSubgrid<'g, V>

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

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

Safety

The area specified by width, height and stride must not overlap with other instances of CutGrid, and the memory region in the area must be valid.

Panics

Panics if width > stride.

pub fn empty() -> Self

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

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

Panic

Panics if:

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

pub fn split_horizontal( &mut self, x: usize, ) -> (MutableSubgrid<'_, V>, MutableSubgrid<'_, V>)

Panics

Panics if x > self.width().

pub fn split_horizontal_in_place(&mut self, x: usize) -> MutableSubgrid<'g, V>

Split the grid horizontally at an index in-place.

Panics

Panics if x > self.width().

pub fn split_vertical( &mut self, y: usize, ) -> (MutableSubgrid<'_, V>, MutableSubgrid<'_, V>)

Split the grid vertically at an index.

Panics

Panics if y > self.height().

pub fn split_vertical_in_place(&mut self, y: usize) -> MutableSubgrid<'g, V>

Split the grid vertically at an index in-place.

Panics

Panics if y > self.height().
