Crate fhe_util

Utilities for the fhe.rs library.

Functions

• catch_unwind
  Define catch_unwind to silence the panic in unit tests.
• inverse
  Computes the modular multiplicative inverse of a modulo p. Returns None if a is not invertible modulo p.
• is_prime
  Returns whether the modulus p is prime; this function is 100% accurate.
• sample_vec_cbd
  Sample a vector of independent centered binomial distributions of a given variance. Returns an error if the variance is strictly larger than 16.
• transcode_bidirectional
  Transcodes a vector of u64 of input_nbits-bit numbers into a vector of u64 of output_nbits-bit numbers.
• transcode_from_bytes
  Transcodes a vector of u8 into a vector of u64 of nbits-bit numbers.
• transcode_to_bytes
  Transcodes a vector of u64 of nbits-bit numbers into a vector of bytes.
• variance
  Compute the sample variance of a list of values. Panics if the length of value is < 2.
