Enum bdk_chain::bitcoin::Network

#[non_exhaustive]
pub enum Network { Bitcoin, Testnet, Testnet4, Signet, Regtest, }
Expand description

The cryptocurrency network to act on.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Bitcoin

Mainnet Bitcoin.

§

Testnet

Bitcoin’s testnet network. (In future versions this will be combined into a single variant containing the version)

§

Testnet4

Bitcoin’s testnet4 network. (In future versions this will be combined into a single variant containing the version)

§

Signet

Bitcoin’s signet network.

§

Regtest

Bitcoin’s regtest network.

Implementations§

§

impl Network

pub fn from_magic(magic: Magic) -> Option<Network>

Creates a Network from the magic bytes.

§Examples
use bitcoin::p2p::Magic;
use bitcoin::Network;

assert_eq!(Ok(Network::Bitcoin), Network::try_from(Magic::from_bytes([0xF9, 0xBE, 0xB4, 0xD9])));
assert_eq!(None, Network::from_magic(Magic::from_bytes([0xFF, 0xFF, 0xFF, 0xFF])));

pub fn magic(self) -> Magic

Return the network magic bytes, which should be encoded little-endian at the start of every message

§Examples
use bitcoin::p2p::Magic;
use bitcoin::Network;

let network = Network::Bitcoin;
assert_eq!(network.magic(), Magic::from_bytes([0xF9, 0xBE, 0xB4, 0xD9]));

pub fn to_core_arg(self) -> &'static str

Converts a Network to its equivalent bitcoind -chain argument name.

$ bitcoin-23.0/bin/bitcoind --help | grep -C 3 '\-chain=<chain>'
Chain selection options:

-chain=<chain>
Use the chain <chain> (default: main). Allowed values: main, test, signet, regtest

pub fn from_core_arg(core_arg: &str) -> Result<Network, ParseNetworkError>

Converts a bitcoind -chain argument name to its equivalent Network.

$ bitcoin-23.0/bin/bitcoind --help | grep -C 3 '\-chain=<chain>'
Chain selection options:

-chain=<chain>
Use the chain <chain> (default: main). Allowed values: main, test, signet, regtest

pub fn chain_hash(self) -> ChainHash

Return the network’s chain hash (genesis block hash).

§Examples
use bitcoin::Network;
use bitcoin::blockdata::constants::ChainHash;

let network = Network::Bitcoin;
assert_eq!(network.chain_hash(), ChainHash::BITCOIN);

pub fn from_chain_hash(chain_hash: ChainHash) -> Option<Network>

Creates a Network from the chain hash (genesis block hash).

§Examples
use bitcoin::Network;
use bitcoin::blockdata::constants::ChainHash;

assert_eq!(Ok(Network::Bitcoin), Network::try_from(ChainHash::BITCOIN));

pub const fn params(self) -> &'static Params

Returns the associated network parameters.
