Function blake3_hash 

Source 
pub fn blake3_hash(data: &[u8]) -> Blake3Digest
Expand description

Computes BLAKE3 hash of the input data.

BLAKE3 is the fastest cryptographic hash function available and supports parallel computation on multi-core systems. It’s based on Bao (verified streaming) and is significantly faster than BLAKE2.

Requires: extended-hashes feature flag

§Performance

BLAKE3 is typically 5-10x faster than SHA-256 and can utilize multiple CPU cores for very large inputs (>16KB). It’s the fastest option in this library.

§Security

BLAKE3 provides 256-bit security (output is 32 bytes by default, but can be extended to any length). It’s designed to be secure against all known attacks.

§Use Cases

  • High-throughput applications (logging, file integrity, checksums)
  • Large file hashing (benefits from parallelization)
  • Content-addressable storage systems
  • Modern replacements for SHA-256 where speed is critical

§Example

ⓘ
use crabgraph::hash::blake3_hash;

let digest = blake3_hash(b"hello world");
assert_eq!(digest.len(), 32);
