Implementations§

impl<'a> Npy<'a>
pub fn is_aligned(&self) -> bool
pub fn is_aligned(&self) -> bool
Checks if the memory buffer is aligned, in which case the data can be referenced in-place.
pub fn as_aligned_ref<E>(&self) -> MatRef<'_, E>where
E: FromNpy,
pub fn as_aligned_ref<E>(&self) -> MatRef<'_, E>where
E: FromNpy,
If the memory buffer is aligned, and the provided type matches the one stored in the buffer, returns a matrix view over the data.
