Function bech32::segwit::encode_upper_to_fmt_unchecked

pub fn encode_upper_to_fmt_unchecked<W: Write>(
    fmt: &mut W,
    hrp: Hrp,
    witness_version: Fe32,
    witness_program: &[u8]
) -> Result

Encodes a segwit address to a writer (fmt::Write) using uppercase characters.

This is provided for use when creating QR codes.

There are no guarantees that the written string is a valid segwit address unless all the parameters are valid. See the body of encode() to see the validity checks required.
