poulpy-cpu-ref 0.5.0

//! Single ring element (`Z[X]/(X^n+1)`) arithmetic for [`NTT120Ref`](crate::NTT120Ref).
//!
//! Implements the `Znx*` traits from `poulpy_hal::reference::znx`. All implementations
//! delegate to the same `_ref` functions as `poulpy-cpu-ref` — these operate on plain
//! `&[i64]` slices, which are backend-independent.
