#[non_exhaustive]
pub enum Network {
Bitcoin,
Testnet,
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.
Signet
Bitcoin’s signet network.
Regtest
Bitcoin’s regtest network.
Implementations§
§impl Network
impl Network
pub fn from_magic(magic: Magic) -> Option<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
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
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>
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
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>
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));
