Enum GroupsType 

pub enum GroupsType {
    Idx(GroupsIdx),
    Slice {
        groups: Vec<[u32; 2]>,
        overlapping: bool,
        monotonic: bool,
    },
}

Variants

Idx(GroupsIdx)

Slice

Fields

groups: Vec<[u32; 2]>

overlapping: bool

Indicates if the groups may overlap, i.e., at least one index MAY be included in more than one group slice.

monotonic: bool

Indicates if the groups are rolling, i.e. for every consecutive group slice (offset, len), and given start = offset and end = offset + len, then both new_start >= start AND new_end >= end MUST be true.

Implementations

impl GroupsType

pub fn new_slice( groups: Vec<[u32; 2]>, overlapping: bool, monotonic: bool, ) -> GroupsType

pub fn into_idx(self) -> GroupsIdx

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

pub fn sort_by_first_idx(&mut self)

pub fn is_overlapping(&self) -> bool

pub fn is_monotonic(&self) -> bool

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

pub fn check_lengths(&self, other: &GroupsType) -> Result<(), PolarsError>

Checks if groups are of equal length. The caller is responsible for updating the groups by calling groups() prior to calling this method.

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.

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

pub fn unwrap_idx(&self) -> &GroupsIdx

Get a reference to the GroupsIdx.

Panic

panics if the groups are a slice.

pub fn unwrap_slice(&self) -> &Vec<[u32; 2]>

Get a reference to the GroupsSlice.

Panic

panics if the groups are an idx.

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

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

Get a mutable reference to the GroupsIdx.

Panic

panics if the groups are a slice.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

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

pub fn into_sliceable(self) -> GroupPositions

pub fn num_elements(&self) -> usize

Trait Implementations

impl AsRef<GroupsType> for GroupPositions

fn as_ref(&self) -> &GroupsType

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for GroupsType

fn clone(&self) -> GroupsType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GroupsType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for GroupsType

fn default() -> GroupsType

Returns the “default value” for a type.

impl Eq for GroupsType

impl From<GroupsIdx> for GroupsType

fn from(groups: GroupsIdx) -> GroupsType

Converts to this type from the input type.

impl PartialEq for GroupsType

fn eq(&self, other: &GroupsType) -> 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.
