pub fn pow_measure_from_data_hash(
data_hash: &Hash,
salt: &Salt,
) -> Result<(Pow, Hash)>Expand description
Core PoW measurement given an already-pre-hashed data blob.
Computes hash(data_hash ++ salt) as the starting point, then runs the
5-round chained-hash algorithm. Use pow_compute_data_hash to produce
data_hash from raw inputs.
