Function bech32::segwit::encode_lower_to_writer_unchecked

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

Encodes a segwit address to a writer (io::Write) using lowercase characters.

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.
