Function generate_key_deterministic 

Source 
pub fn generate_key_deterministic<const W: usize, const H: usize>(
    rng: &mut ChaCha20Rng,
) -> Zeroizing<Vec<i64>>
Expand description

Generates a deterministic key vector using a ChaCha20-based DRNG.

This function produces a Vec<i64> of length $2 \times W \times H$ by sampling from the provided ChaCha20 random number generator. Each value is derived from a u64 output and cast to i64.

§Parameters

  • rng: A mutable reference to a seeded ChaCha20Rng instance.

§Returns

A vector of signed 64-bit integers representing raw key material.

§Notes

  • The output is deterministic for a given RNG seed.
