Trait RowSource 

Source 
pub trait RowSource {
    // Required method
    fn next_row(&mut self) -> ExecResult<Option<Row>>;
}
Expand description

Fallible pull-based row cursor.

Each call to RowSource::next_row returns the next row, Ok(None) when the cursor is exhausted, or an error if execution fails. The cursor stays in a valid state after an error — callers may drop it without observing additional side effects.

Required Methods§

Source

fn next_row(&mut self) -> ExecResult<Option<Row>>

Pull the next row.
