pub struct ImageIndex { /* private fields */ }

The image side of the search: every star’s position, a position hash, and the star pairs sorted by length. Built once per image.

Implementations

impl ImageIndex

pub fn new(pos: Vec<(f64, f64)>, max_pair_px: f64, probe_tol: f64) -> Self

Index pos (pixels) for probes within probe_tol pixels, and the pairs among them no longer than max_pair_px.

pub fn len(&self) -> usize

Number of indexed stars.

pub fn is_empty(&self) -> bool

Whether no star is indexed.

pub fn n_pairs(&self) -> usize

Number of indexed pairs.
