Struct JoinKeyBinding 

pub struct JoinKeyBinding {
    pub build_col: u32,
    pub probe_col: u32,
    pub build_map_key: Option<String>,
    pub probe_map_key: Option<String>,
}

Resolved join key binding for one equality condition: which build/probe columns participate, and whether the column holds a map/struct from which a key must be extracted (e.g. UNWIND $rows AS row MATCH (m:Memory {id: row.id}) binds the probe column row with map key id, P53.26).

Fields

build_col: u32

probe_col: u32

build_map_key: Option<String>

Map key to extract from the build-side column value (None = raw cell).

probe_map_key: Option<String>

Map key to extract from the probe-side column value (None = raw cell).
