Implementations§

Source§

impl GroupsProxy

Source

pub fn into_idx(self) -> GroupsIdx

Source

pub fn iter(&self) -> GroupsProxyIter<'_>

Source

pub fn sort(&mut self)

Source

pub fn take_group_firsts(self) -> Vec<IdxSize>

Source

pub unsafe fn take_group_lasts(self) -> Vec<IdxSize>

§Safety

This will not do any bounds checks. The caller must ensure all groups have members.

Source

pub fn par_iter(&self) -> GroupsProxyParIter<'_>

Source

pub fn unwrap_idx(&self) -> &GroupsIdx

Get a reference to the GroupsIdx.

§Panic

panics if the groups are a slice.

Source

pub fn unwrap_slice(&self) -> &GroupsSlice

Get a reference to the GroupsSlice.

§Panic

panics if the groups are an idx.

Source

pub fn get(&self, index: usize) -> GroupsIndicator<'_>

Source

pub fn idx_mut(&mut self) -> &mut GroupsIdx

Get a mutable reference to the GroupsIdx.
