num-primes uses thread_rng() internally, making its benchmarks
non-deterministic and causing false regressions in CodSpeed CI.
Remove num-primes from default features so it's excluded from CI
benchmarks. All num-primes bench_functions are gated behind
#[cfg(feature = "num-primes")] - use --features num-primes to
include them for local comparison.
num-primes uses thread_rng() internally, making its benchmarks
non-deterministic. CodSpeed's instruction-counting simulation
amplifies this into huge false regressions. Gate all num-primes
bench_functions with #[cfg(feature = "num-primes")] and build
without the feature in CodSpeed CI.
- Update tsqrt bound after extracting factors in trial division
- Reorder primality check to after trial division in factorize64
- Add 5th/7th perfect power checks in factorize128_advanced
- Add #[inline] on is_prime64, is_prime64_miller, is_prime32_miller
- Pre-allocate vectors in factorization and primality functions
- Use /= in trial division inner loops
Reproduces the panic that occurs when calling nth_root_exact with even
roots on negative numbers, which should return None instead of panicking.
