[−][src]Struct tsxlib::joins::JoinEngine

pub struct JoinEngine<'a, TIndex: Serialize + Hash + Clone + Eq + Ord> {
    pub idx_this: &'a HashableIndex<TIndex>,
    pub idx_other: &'a HashableIndex<TIndex>,
}

JoinEngine is responsible for join logic, it consists of two indicies. idx_this is the LHS and idx_other is the RHS. Indicies are passed by reference

Fields

idx_this: &'a HashableIndex<TIndex>idx_other: &'a HashableIndex<TIndex>

Implementations

impl<'a, TIndex: Serialize + Hash + Clone + Eq + Ord> JoinEngine<'a, TIndex>[src]

pub fn get_inner_hash_joined_indicies(&self) -> Vec<IndexJoinPair>[src]

Hash inner join

pub fn get_left_hash_joined_indicies(
    &self
) -> Vec<IndexJoinPotentiallyUnmatchedPair>[src]

Hash join left. All left values are joined so no Option on the base index

pub fn get_left_merge_joined_indicies(
    &self
) -> Vec<IndexJoinPotentiallyUnmatchedPair>[src]

Left Merge Join

pub fn get_inner_merge_joined_indicies(&self) -> Vec<IndexJoinPair>[src]

merge sort join join a and b.

pub fn get_asof_merge_joined_indicies(
    &self,
    compare_func: Option<Box<dyn Fn(&TIndex, &TIndex, &TIndex) -> (Ordering, i64)>>,
    other_idx_func: Option<Box<dyn Fn(usize) -> usize>>
) -> Vec<IndexJoinPotentiallyUnmatchedPair>[src]

as of join. this is a variation of merge join that allows for indicies to be equal based on a custom comperator func
