Module join 

Generic JOIN execution primitives.

This module contains type-independent JOIN control flow. Callers provide concrete row storage, predicate evaluation, key extraction, row construction, and null value construction.

Traits

RowLike

Minimal row interface required by generic JOIN row-combination helpers.

Functions

combine_rows

Combine left and right row values into a caller-owned output row.

hash_join

Execute a generic hash join for equi-joins.

nested_loop_join

Execute a generic nested-loop join.

pad_left

Combine a right row with left-side null padding.

pad_right

Combine a left row with right-side null padding.

Type Aliases

JoinPair

A generic joined row pair emitted by JOIN control-flow primitives.

JoinPairs

Generic joined row pairs emitted by JOIN control-flow primitives.
