Bech32 Rust
Rust implementation of the Bech32 encoding format described in BIP-0173. You can find some usage examples in the documentation.
Bitcoin-specific address encoding is handled by the bitcoin-bech32
crate.

Encoding and decoding of the Bech32 format
Bech32 is an encoding scheme that is easy to use for humans and efficient to encode in QR codes.
A Bech32 string consists of a human-readable part (HRP), a separator (the character '1'
), and a data part.
A checksum at the end of the string provides error detection to prevent mistakes when the string is written off or read out loud.
The original description in BIP-0173 has more details.
Examples
use bech32::{self, FromBase32, ToBase32};
let encoded = bech32::encode("bech32", vec![0x00, 0x01, 0x02].to_base32()).unwrap();
assert_eq!(encoded, "bech321qqqsyrhqy2a".to_string());
let (hrp, data) = bech32::decode(&encoded).unwrap();
assert_eq!(hrp, "bech32");
assert_eq!(Vec::<u8>::from_base32(&data).unwrap(), vec![0x00, 0x01, 0x02]);
