Enum polars::frame::group_by::GroupsProxy

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

Available on crate feature algorithm_group_by only.

Variants

Idx(GroupsIdx)

Slice

Slice is always sorted in ascending order.

Fields

groups: Vec<[u32; 2]>

rolling: bool

Implementations

impl GroupsProxy

pub fn into_idx(self) -> GroupsIdx

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

pub fn sort(&mut self)

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

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

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) -> GroupsProxyParIter<'_>

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 unroll(self) -> GroupsProxy

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

Trait Implementations

impl Clone for GroupsProxy

fn clone(&self) -> GroupsProxy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GroupsProxy

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

Formats the value using the given formatter.

impl Default for GroupsProxy

fn default() -> GroupsProxy

Returns the “default value” for a type.

impl From<GroupsIdx> for GroupsProxy

fn from(groups: GroupsIdx) -> GroupsProxy

Converts to this type from the input type.

impl PartialEq for GroupsProxy

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

This method tests for self and other values to be equal, and is used by ==.

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

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