    Testnet,
    Signet,
    Regtest,
}

Variants (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.

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::network::constants::{Network, Magic};
use std::convert::TryFrom;

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::network::constants::{Network, Magic};

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::constants::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::constants::Network;
use bitcoin::blockdata::constants::ChainHash;
use std::convert::TryFrom;

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

Parses a string s to return a value of this type.

impl Hash for Network

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,
