Struct JoinKeyPair 

pub struct JoinKeyPair {
    pub stream_expr: Expr,
    pub lookup_column: String,
}

A pair of expressions defining how stream keys map to lookup columns.

Fields

stream_expr: Expr

Expression on the stream side (e.g., stream.customer_id).

lookup_column: String

Column name on the lookup table side.

Trait Implementations

impl Clone for JoinKeyPair

fn clone(&self) -> JoinKeyPair

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinKeyPair

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

Formats the value using the given formatter.

impl Hash for JoinKeyPair

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

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 JoinKeyPair

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