Bech32 Rust

Rust implementation of the Bech32 encoding format described in BIP-0173.

Bitcoin-specific address encoding is handled by the bitcoin-bech32 crate.

Examples

use bech32::Bech32;

let b = Bech32::new_check_data("bech32".into(), vec![0x00, 0x01, 0x02]).unwrap();
let encoded = b.to_string();
assert_eq!(encoded, "bech321qpz4nc4pe".to_string());

let c = encoded.parse::<Bech32>();
assert_eq!(b, c.unwrap());

If the data is already range-checked the Bech32::new function can be used which will never return Err(Error::InvalidData).

use bech32::{Bech32, u5, ToBase32};

// converts base256 data to base32 and adds padding if needed
let checked_data: Vec<u5> = [0xb4, 0xff, 0xa5].to_base32();

let b = Bech32::new("bech32".into(), checked_data).expect("hrp is not empty");
let encoded = b.to_string();

assert_eq!(encoded, "bech321knl623tk6v7".to_string());
