Struct PowerTable

Source

pub struct PowerTable<R>where
    R: RingStore,
{ /* private fields */ }

Expand description

Contains an implementation of the slot-broadcast transform.

Provides access to arbitrary powers of a single element of a finite ring, caching intermediate powers for faster access.

The main use case are HE-style rings, in which multiplication can be quite expensive.
