Enum polars_lazy::dsl::WindowType

pub enum WindowType {
    Over(WindowMapping),
    Rolling(RollingGroupOptions),
}

Variants

Over(WindowMapping)

Explode the aggregated list and just do a hstack instead of a join this requires the groups to be sorted to make any sense

Rolling(RollingGroupOptions)

Available on crate feature dynamic_group_by only.

Trait Implementations

impl Clone for WindowType

fn clone(&self) -> WindowType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowType

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

Formats the value using the given formatter.

impl Default for WindowType

fn default() -> WindowType

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WindowType

fn deserialize<__D>( __deserializer: __D ) -> Result<WindowType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<WindowMapping> for WindowType

fn from(value: WindowMapping) -> WindowType

Converts to this type from the input type.

impl Hash for WindowType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WindowType

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

impl Serialize for WindowType

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for WindowType

impl StructuralPartialEq for WindowType
