Struct RowsBatchRef

pub struct RowsBatchRef<'a, T> { /* private fields */ }

This struct is similar to RowsBatch, but it holds a reference to the slice of rows. Unfortunately due to liftime issues we can’t have a single generic struct which is parameterized by a container type.

Implementations

impl<'a, T> RowsBatchRef<'a, T>

pub fn new(rows: &'a [&'a [T]], row_len: usize) -> Self

Create a new RowsBatchRef from a slice of rows and the given row length.

Panics

In case if any of the rows has a length different from n_cols.

pub fn iter(&self) -> impl Iterator<Item = &'a [T]> + '_

pub fn rows(&self) -> &[&'a [T]]

pub fn n_rows(&self) -> usize

pub fn row_len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn map(&self, indices: impl AsRef<[usize]>) -> RowsBatch<'a, T>
