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 group_lengths(&self, name: &str) -> ChunkedArray<UInt32Type>

source

pub fn take_group_firsts(self) -> Vec<u32>

source

pub unsafe fn take_group_lasts(self) -> Vec<u32>

§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) -> &Vec<[u32; 2]>

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.

§Panic

panics if the groups are a slice.

source

pub fn len(&self) -> usize

source

pub fn is_empty(&self) -> bool

source

pub fn group_count(&self) -> ChunkedArray<UInt32Type>

source

pub fn as_list_chunked(&self) -> ChunkedArray<ListType>

source

pub fn unroll(self) -> GroupsProxy

source

pub fn slice(&self, offset: i64, len: usize) -> SlicedGroups<'_>
