Struct genmesh::LruIndexer
[−]
[src]
pub struct LruIndexer<T, F: FnMut(usize, T)> { /* fields omitted */ }
An LruIndexer is useful for creating indexed steam from a stream of
vertices. Each vertex that is index is only compared against the vetices
contained in the cache. If a vertex is not found the LruIndexer will emit
a new vertex and return the index of that new vertex.
The oldest sample by time used will be dropped if a new vertex is found.
Methods
impl<T, F: FnMut(usize, T)> LruIndexer<T, F>[src]
fn new(size: usize, emit: F) -> LruIndexer<T, F>
create a new LruIndexer, the window size is limited by the size parameter
it is recommended to keep this small since lookup is done in N time
if a new vertex is found, emit will be called. emit will be supplied with a
vertex and a index that was used.
