AsofDirection

laminar_core::operator::asof_join

Enum AsofDirection 

Source 
pub enum AsofDirection {
    Backward,
    Forward,
    Nearest,
}
Expand description

Direction for ASOF matching.

Variants§

§

Backward

Match with the most recent prior event (timestamp <= left timestamp). This is the default and most common for financial applications.

§

Forward

Match with the next future event (timestamp >= left timestamp).

§

Nearest

Match with the closest event by absolute time difference.
