Struct GroupsIdx 

pub struct GroupsIdx { /* private fields */ }

Available on crate feature algorithm_group_by only.

Indexes of the groups, the first index is stored separately. this make sorting fast.

fn from_par_iter<I>(par_iter: I) -> Self

where I: IntoParallelIterator<Item = IdxItem>,

Creates an instance of the collection from the parallel iterator par_iter.

impl<'a> IntoIterator for &'a GroupsIdx

type Item = (u32, &'a UnitVec<u32>)

The type of the elements being iterated over.

type IntoIter = Zip<Copied<Iter<'a, u32>>, Iter<'a, UnitVec<u32>>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

The type of the elements being iterated over.

type IntoIter = Zip<IntoIter<u32>, IntoIter<UnitVec<u32>>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoParallelIterator for &'a GroupsIdx

type Iter = Zip<Copied<Iter<'a, u32>>, Iter<'a, UnitVec<u32>>>

The parallel iterator type that will be created.

type Item = (u32, &'a UnitVec<u32>)

The type of item that the parallel iterator will produce.

impl PartialEq for GroupsIdx

fn eq(&self, other: &GroupsIdx) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
