Struct npy::NpyData

pub struct NpyData<'a, T> { /* fields omitted */ }

The data structure representing a deserialized npy file.

The data is internally stored as a byte array, and deserialized only on-demand to minimize unnecessary allocations. The whole contents of the file can be deserialized by the to_vec member function.

Methods

impl<'a, T: Serializable> NpyData<'a, T>

pub fn from_bytes(bytes: &'a [u8]) -> Result<NpyData<'a, T>>

Deserialize a NPY file represented as bytes

pub fn get(&self, i: usize) -> Option<T>

Gets a single data-record with the specified index. Returns None, if the index is out of bounds

pub fn len(&self) -> usize

Returns the total number of records

pub fn is_empty(&self) -> bool

Returns whether there are zero records in this NpyData structure

pub fn get_unchecked(&self, i: usize) -> T

Gets a single data-record wit the specified index. Panics, if the index is out of bounds.

pub fn to_vec(&self) -> Vec<T>

Construct a vector with the deserialized contents of the whole file

Trait Implementations

impl<'a, T: 'a + Serializable> IntoIterator for NpyData<'a, T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
