Struct Atlas 

pub struct Atlas { /* private fields */ }

Atlas: previously decoded patches, ranked lookup by signature.

Implementations

impl Atlas

pub fn new() -> Self

Empty atlas at the header capacity.

pub fn insert(&mut self, tile: &Tile)

Insert a decoded tile (encoder-side bookkeeping).

pub fn insert_with_sig(&mut self, tile: &Tile, sig: Sig)

Insert with a precomputed signature (review fix 5: callers that already computed sig for ranking should not pay for it twice).

pub fn rank_by_sig(&self, sig: &Sig, w: u32, h: u32, top: usize) -> Vec<u32>

Rank candidate patch indices by structural signature distance (v0.6 P1: gradient/variance/luma, not mean-RGB-only). Only identically shaped patches within the last ATLAS_CAPACITY (README: “last 128”) are eligible. Returns at most top indices, best first — encoder re-scores each candidate by actual proxy cost anyway.

Trait Implementations

impl Default for Atlas

fn default() -> Self

Returns the “default value” for a type.
