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

```rust use bech32::Bech32;

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

let c = encoded.parse::(); 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).

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

// converts base256 data to base32 and adds padding if needed let checkeddata: Vec = [0xb4, 0xff, 0xa5].tobase32();

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

asserteq!(encoded, "bech321knl623tk6v7".tostring()); ```
