Struct FrameCache 

struct FrameCache {
    map: HashMap<u64, VideoFrame>,
    order: Vec<u64>,
    capacity: usize,
}

A small LRU cache of decoded frames keyed by frame index.

Fields

map: HashMap<u64, VideoFrame>

order: Vec<u64>

Frame indices in least-recently-used order (LRU at the front).

capacity: usize
