Struct Reader 

pub struct Reader<R: BufRead> { /* private fields */ }

A streaming, event-based SIF reader.

Reads lines from any BufRead source and yields Event values one at a time via next_event().

use sif_parser::{Reader, Event};
let mut reader = Reader::from_str(sif_text);
while let Some(event) = reader.next_event()? {
    match event {
        Event::Record(r) => { /* process record */ }
        _ => {}
    }
}
