Enum JoinBy

pub enum JoinBy {
    AddColumns,
    Replace,
    Extend,
    Broadcast,
    CartesianProduct,
    JoinById(JoinById),
}

Enum representing different strategies for combining or joining data structures.

Variants

AddColumns

Adds only non-existing columns to the existing structure. This is the default behavior.

Replace

Replaces existing data with the new data.

Extend

Extends the existing data by appending new elements.

Broadcast

Performs a broadcast operation, replicating smaller data structures to match the size of larger ones.

CartesianProduct

Computes the Cartesian product of the input structures, resulting in all possible combinations of elements.

JoinById(JoinById)

Joins two structures using a specific identifier or key.

The behavior is determined by the provided JoinById variant.

Trait Implementations

impl Clone for JoinBy

fn clone(&self) -> JoinBy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JoinBy

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

Formats the value using the given formatter.

impl Default for JoinBy

fn default() -> JoinBy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JoinBy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JoinBy

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

impl Serialize for JoinBy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
