Struct Selection 

pub struct Selection { /* private fields */ }

A selection of column indices.

Implementations

impl Selection

pub fn full(len: usize) -> Self

pub fn without(i: usize, len: usize) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn select<'a, 'b, T: 'b + ?Sized>( &'a self, row: &'b impl Index<usize, Output = T>, ) -> impl Iterator<Item = &'b T>

where 'a: 'b,

pub fn iter(&self) -> Copied<Iter<'_, usize>>

pub fn indexed_mask(&self) -> Vec<Option<usize>>

pub fn mask(&self) -> Vec<bool>

Trait Implementations

impl Index<usize> for Selection

type Output = usize

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a> IntoIterator for &'a Selection

type Item = usize

The type of the elements being iterated over.

type IntoIter = Copied<Iter<'a, usize>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
