Trait Collector 

pub trait Collector {
    // Required method
    fn collect(
        &mut self,
        doc_id: DocId,
        score: Score,

    fn needs_positions(&self) -> bool { ... }
}

Trait for search result collectors

Implement this trait to create custom collectors that can be combined and passed to query execution.

Required Methods

fn collect( &mut self, doc_id: DocId, score: Score, positions: &[(u32, Vec<ScoredPosition>)], )

Called for each matching document positions: Vec of (field_id, scored_positions)

Provided Methods

fn needs_positions(&self) -> bool

Whether this collector needs position information
