Struct FrameHashStore 

pub struct FrameHashStore { /* private fields */ }

In-memory store of FrameHash values supporting similarity search.

Implementations

impl FrameHashStore

pub fn new() -> Self

Create an empty store.

pub fn insert(&mut self, hash: FrameHash)

Insert a FrameHash into the store, keyed by its frame_index.

pub fn find_similar( &self, query: &FrameHash, max_distance: u32, ) -> Vec<(u64, u32)>

Find all hashes within max_distance of query.

Returns a Vec of (frame_index, distance) pairs sorted by distance.

pub fn count(&self) -> usize

Return the total number of hashes in the store.

pub fn remove(&mut self, frame_index: u64) -> Option<FrameHash>

Remove the hash for a given frame index, returning it if present.

pub fn contains(&self, frame_index: u64) -> bool

Check whether the store contains a hash for frame_index.
