Implementations

impl<'a, T, R, C, RStride, CStride> ViewStorageMut<'a, T, R, C, RStride, CStride>

where R: Dim, C: Dim, RStride: Dim, CStride: Dim,

pub unsafe fn from_raw_parts( ptr: *mut T, shape: (R, C), strides: (RStride, CStride), ) -> ViewStorageMut<'a, T, R, C, RStride, CStride>

where RStride: Dim, CStride: Dim,

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].

where R: Dim, C: Dim,

pub unsafe fn new_unchecked<RStor, CStor, S>( storage: &'a mut S, start: (usize, usize), shape: (R, C), ) -> ViewStorageMut<'a, T, R, C, <S as RawStorage<T, RStor, CStor>>::RStride, <S as RawStorage<T, RStor, CStor>>::CStride>

where RStor: Dim, CStor: Dim, S: RawStorageMut<T, RStor, CStor>,

Safety

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

where RStor: Dim, CStor: Dim, S: RawStorageMut<T, RStor, CStor>, RStride: Dim, CStride: Dim,

Create a new matrix view without bounds checking.

Safety

strides must be a valid stride indexing.
