Trait sql_ops::join::no_partitioning_join::CpuHashJoinable

pub trait CpuHashJoinable: DeviceCopy + KeyAttribute {
    fn build_impl(
        hj: &mut CpuHashJoin<Self>, 
        join_attr: &[Self], 
        payload_attr: &[Self]
    ) -> Result<()>;
    fn probe_sum_impl(
        hj: &mut CpuHashJoin<Self>, 
        join_attr: &[Self], 
        payload_attr: &[Self], 
        join_result: &mut u64
    ) -> Result<()>;
}

Specifies that the implementing type can be used as a join key in CpuHashJoin.

See CudaHashJoinable for more details on the design decision.
