Struct Matcher 

pub struct Matcher<T> { /* private fields */ }

A prebuilt, declination-sorted index for repeated queries against one catalogue.

Produces results identical to rank for the same objects, pointing, and constraint — the index is a performance optimization only. Build it once, then query many pointings.

Implementations

impl<T: SkyObject> Matcher<T>

pub fn from_objects(objects: Vec<T>) -> Self

Build an index from a set of objects (original order is preserved for tie-breaking and objects).

pub fn objects(&self) -> &[T]

The stored objects, in their original insertion order.

pub fn query(&self, pointing: Equatorial, c: Constraint) -> Vec<Match<'_, T>>

Query the index for a pointing under a constraint.

pub fn is_framed<'a>( &self, pointing: Equatorial, object: &'a T, m: Membership, ) -> Match<'a, T>

Evaluate a single stored-or-external object against a frame (see is_framed).
