}

Required Methods§

Source

fn append_matched_row( op: Op, builder: &mut StreamChunkBuilder, left_row: impl Row, right_row: impl Row, ) -> Option<StreamChunk>

Called when a matched row is found.

Source

fn match_end( builder: &mut StreamChunkBuilder, op: Op, left_row: impl Row, right_size: usize, matched: bool, ) -> Option<StreamChunk>

Called when all matched rows of a join key are appended.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
