}Provided Methods
sourceunsafe fn at_unchecked_mut<T: DataType>(&mut self, i0: i32) -> Result<&mut T>
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
sourceunsafe fn at_2d_unchecked_mut<T: DataType>(
&mut self,
row: i32,
col: i32
) -> Result<&mut T>
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
sourceunsafe fn at_pt_unchecked_mut<T: DataType>(
&mut self,
pt: Point
) -> Result<&mut T>
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
sourceunsafe fn at_3d_unchecked_mut<T: DataType>(
&mut self,
i0: i32,
i1: i32,
i2: i32
) -> Result<&mut T>
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
sourceunsafe fn at_nd_unchecked_mut<T: DataType>(
&mut self,
idx: &[i32]
) -> Result<&mut T>
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

) -> Result<&mut [T]>
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
sourcefn set(&mut self, s: Scalar) -> Result<()>
fn set(&mut self, s: Scalar) -> Result<()>
Sets all or some of the array elements to the specified value.
Parameters
- s: Assigned scalar converted to the actual array type.
sourcefn data_bytes_mut(&mut self) -> Result<&mut [u8]>
fn data_bytes_mut(&mut self) -> Result<&mut [u8]>
Returns underlying data array as mutable byte slice, Mat must be continuous.
