Crate rspow 

RSPOW: simple multi-algorithm proof-of-work utilities.

Supported algorithms:

• SHA-256, SHA-512, RIPEMD-320
• Scrypt, Argon2id (with custom Params)

Difficulty modes:

• AsciiZeroPrefix (default): hash must start with difficulty bytes of ASCII ‘0’ (0x30).
• LeadingZeroBits: hash must have at least difficulty leading zero bits (big-endian within bytes).

Quick examples:

use rspow::{PoW, PoWAlgorithm};

let data = "hello";
let algorithm = PoWAlgorithm::Sha2_256;
let pow = PoW::new(data, 2, algorithm).unwrap();
let target = pow.calculate_target();
let (_hash, _nonce) = pow.calculate_pow(&target);

use rspow::{PoW, PoWAlgorithm, DifficultyMode};

let data = "hello";
let pow = PoW::with_mode(data, 10, PoWAlgorithm::Sha2_256, DifficultyMode::LeadingZeroBits).unwrap();
let (_hash, _nonce) = pow.calculate_pow(&[]); // target ignored in bits mode
