Expand description

Compiled join configuration. Dotted key paths are pre-split at construction.

Fields§

§mode: JoinMode

Inner vs left.

§build_key: String

Dotted path to the build-side (right) key.

§probe_key: String

Dotted path to the probe-side (left) key.

§projections: Vec<Projection>

Fields to copy from the build record onto the probe record.

§on_missing: Value

Value used to fill projected fields on a left-mode non-match.

§on_duplicate: OnDuplicate

Multi-match policy.

§on_collision: OnCollision

Projection-collision policy.

§key_normalize: KeyNormalize

Key-normalization policy.

§max_build_records: usize

Safety cap on build-side records.
