Struct bitcoin_bech32::WitnessProgram

pub struct WitnessProgram { /* fields omitted */ }

Witness version and program data

Methods

impl WitnessProgram

pub fn new(     version: u5,     program: Vec<u8>,     network: Network ) -> Result<WitnessProgram, Error>

Construct a new WitnessProgram given the constituent version, witness program and network version

pub fn to_address(&self) -> String

Converts a Witness Program to a SegWit Address

pub fn from_address(address: &str) -> Result<WitnessProgram, Error>

Decodes a segwit address into a Witness Program

Verifies that the address contains a known human-readable part hrp and decodes as proper Bech32-encoded string. Allowed values of the human-readable part correspond to the defined types in constants

Important traits for Vec<u8>

impl Write for Vec<u8>

pub fn to_scriptpubkey(&self) -> Vec<u8>

Converts a WitnessProgram to a script public key

The format for the output is [version, program length, <program>]

pub fn from_scriptpubkey(     pubkey: &[u8],     network: Network ) -> Result<WitnessProgram, Error>

Extracts a WitnessProgram out of a provided script public key

pub fn validate(&self) -> Result<(), Error>

Validates the WitnessProgram against version and length constraints

pub fn version(&self) -> u5

Witness program version

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

pub fn program(&self) -> &[u8]

Witness program serialized as 8-bit bytes

pub fn network(&self) -> Network

Which network this witness program is intended to be run on
