Struct extendr_api::prelude::io::Npy

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

Memory view over a buffer in npy format.

Implementations

impl<'a> Npy<'a>

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

Parse a npy file from a memory buffer.

pub fn dtype(&self) -> NpyDType

Returns the data type of the memory buffer.

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,

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

pub fn to_mat<E>(&self) -> Mat<E>

where E: FromNpy,

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