Function parallel_hash 

pub fn parallel_hash(data: &[u8]) -> [u8; 32]

Parallel hash computation for large data

Splits the input into chunks and computes hashes in parallel using multiple threads, then combines the results using BLAKE3’s tree hashing.

Arguments

• data - Input data to hash

Returns

32-byte BLAKE3 hash digest

Performance

For data larger than 16KB, this function uses parallel processing. Smaller data uses single-threaded hashing for lower overhead.
