Struct Lane 

Source 
pub struct Lane<C> {
    pub query_weight: Weight,
    pub cursor: C,
}
Expand description

One query dimension paired with its cursor.

Fields§

§query_weight: Weight§cursor: C

Implementations§

Source§

impl<C: PostingCursor> Lane<C>

Source

pub fn new(query_weight: Weight, cursor: C) -> Self

Source

pub fn current_id(&self) -> Option<RecordId>

Id the cursor is on, if any.

Source

pub fn headroom(&self) -> f64

The most this lane can add to the score of any record not yet consumed by its cursor. A record absent from the lane adds nothing, so the bound is never below zero.
