Struct Npy

pub struct Npy<'a> { /* private fields */ }

Expand description

memory view over a buffer in npy format

Implementations§

Source §

impl<'a> Npy<'a>

Source

pub fn new(data: &'a [u8]) -> Result<Self, Error>

parse a npy file from a memory buffer

Source

pub fn dtype(&self) -> NpyDType

returns the data type of the memory buffer

Source

pub fn is_aligned(&self) -> bool

checks if the memory buffer is aligned, in which case the data can be referenced in-place

Source

pub fn as_aligned_ref<T: FromNpy>(&self) -> MatRef<'_, T>

if the memory buffer is aligned, and the provided type matches the one stored in the buffer, returns a matrix view over the data

Source

pub fn to_mat<T: FromNpy>(&self) -> Mat<T>

if the provided type matches the one stored in the buffer, returns a matrix containing the data
