sourcepub unsafe fn from_raw_parts(

shape: (R, C),
strides: (RStride, CStride)
) -> Self
pub unsafe fn from_raw_parts( ptr: *mut T, shape: (R, C), strides: (RStride, CStride) ) -> Self
Create a new matrix view without bounds checking and from a raw pointer.
§Safety
*ptr
must point to memory that is valid [T; R * C]
.

§Safety
storage
contains sufficient elements beyond start + R * C
such that all
accesses are within bounds.
