pub fn solve(a: &[Vec<u8>], b: &[u8]) -> Option<Vec<u8>>Expand description
A particular solution of A x = b over GF(2^8), or None if the system is
inconsistent. a is m×n (row per equation), b has length m; the returned x
has length n with free variables set to zero. When the caller knows the system is
square and full-rank (Oil-and-Vinegar signing after fixing the vinegar variables),
the solution is unique.
