Provided Methods§

Source

unsafe fn at_unchecked_mut<T: DataType>(&mut self, i0: i32) -> Result<&mut T>

Like Mat::at_mut() but performs no bounds or type checks

§Safety

Caller must ensure that index is within Mat bounds

Source

unsafe fn at_2d_unchecked_mut<T: DataType>( &mut self, row: i32, col: i32, ) -> Result<&mut T>

Like Mat::at_2d_mut() but performs no bounds or type checks

§Safety

Caller must ensure that indices are within Mat bounds

Source

unsafe fn at_pt_unchecked_mut<T: DataType>( &mut self, pt: Point, ) -> Result<&mut T>

Like Mat::at_pt_mut() but performs no bounds or type checks

§Safety

Caller must ensure that point is within Mat bounds

Source

unsafe fn at_3d_unchecked_mut<T: DataType>( &mut self, i0: i32, i1: i32, i2: i32, ) -> Result<&mut T>

Like Mat::at_3d_mut() but performs no bounds or type checks

§Safety

Caller must ensure that indices are within Mat bounds

Source

unsafe fn at_nd_unchecked_mut<T: DataType>( &mut self, idx: &[i32], ) -> Result<&mut T>

Like Mat::at_nd_mut() but performs no bounds or type checks

§Safety

Caller must ensure that indices are within Mat bounds

Source

fn at_row_mut<T: DataType>(&mut self, row: i32) -> Result<&mut [T]>

Return a complete writeable row

Source

unsafe fn at_row_unchecked_mut<T: DataType>( &mut self, row: i32, ) -> Result<&mut [T]>

Like Mat::at_row_mut() but performs no bounds or type checks

§Safety

Caller must ensure that index is within Mat bounds

Source

fn data_bytes_mut(&mut self) -> Result<&mut [u8]>

Returns underlying data array as mutable byte slice, Mat must be continuous.

Source

fn data_typed_mut<T: DataType>(&mut self) -> Result<&mut [T]>

Source

unsafe fn data_typed_unchecked_mut<T: DataType>(&mut self) -> Result<&mut [T]>

§Safety

Caller must ensure that the T type argument corresponds to the data stored in the Mat and Mat is continuous

Source

fn iter_mut<T: DataType>(&mut self) -> Result<MatIterMut<'_, T>>
where Self: Sized,

Returns a mutable iterator over Mat elements and their positions

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
