Bech32Address and Bech32ContractId enable the use of addresses and contract ids in the bech32 format. They can easily be converted to their counterparts Address and ContractId.

Here are the main ways of creating a Bech32Address, but note that the same applies to Bech32ContractId:

        use fuels::{
            tx::{Address, Bytes32},

        // New from HRP string and a hash
        let hrp = "fuel";
        let my_slice = [1u8; 32];
        let _bech32_address = Bech32Address::new(hrp, my_slice);

        // Note that you can also pass a hash stored as Bytes32 to new:
        let my_hash = Bytes32::new([1u8; 32]);
        let _bech32_address = Bech32Address::new(hrp, my_hash);

        // From a string.
        let address = "fuel1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqsx2mt2";
        let bech32_address =
            Bech32Address::from_str(address).expect("failed to create Bech32 address from string");
        assert_eq!([0u8; 32], *bech32_address.hash());

        // From Address
        let plain_address = Address::new([0u8; 32]);
        let bech32_address = Bech32Address::from(plain_address);
        assert_eq!([0u8; 32], *bech32_address.hash());

        // Convert to Address
        let _plain_address: Address = bech32_address.into();

Note: when creating a Bech32Address from Address or Bech32ContractId from ContractId the HRP (Human-Readable Part) is set to "fuel" per default.
