Implementations

impl Network

pub const fn magic(self) -> [u8; 4]

Returns the four P2P message-start bytes in wire order.

pub const fn default_p2p_port(self) -> u16

Returns the default P2P port.

pub const fn bip34_activation_height(self) -> u32

Returns the network’s BIP34 coinbase-height activation height.

Per Bitcoin Core’s chainparams.cpp for fixed public networks:

• Mainnet activates at height 227,931
• Testnet3 activates at height 21,111
• Testnet4 / Signet activate at height 1
• This crate’s deterministic regtest default activates at height 500.

pub const fn bip34_activation_hash(self) -> Option<Hash256>

Returns the fixed BIP34 activation block hash when Core uses one to prove that BIP34 implies BIP30 on a known chain.

pub const fn is_bip34_active(self, height: u32) -> bool

Returns true when BIP34 coinbase-height encoding is enforced at height.

pub const fn is_bip65_active(self, height: u32) -> bool

Returns true when BIP65 (OP_CHECKLOCKTIMEVERIFY) is enforced at height.

Per Bitcoin Core’s chainparams.cpp:

• Mainnet activates at height 388,381
• Testnet3 activates at height 581,885
• Testnet4 / Signet activate at height 1
• Regtest activates at height 1,351

pub const fn is_bip66_active(self, height: u32) -> bool

Returns true when BIP66 (strict DER signatures) is enforced at height.

pub const fn is_csv_active(self, height: u32) -> bool

Returns true when CSV (BIP68/112/113 relative locktime + MTP) is enforced at height.

pub const fn is_segwit_active(self, height: u32) -> bool

Returns true when Segwit (BIP141/143/147) is enforced at height.

pub const fn is_taproot_active(self, height: u32) -> bool

Returns true when Taproot (BIP341/342) is enforced at height.

pub const fn default_rpc_port(self) -> u16

Returns the default JSON-RPC port used by Bitcoin Core.

pub const fn dns_seeds(self) -> &'static [&'static str]

Returns DNS seeds from Bitcoin Core chain parameters.

pub const fn max_target(self) -> Uint<256, 4>

Returns the proof-of-work limit target.

pub const fn retarget_interval(self) -> u32

Returns the main retarget interval in blocks.

pub const fn target_spacing_seconds(self) -> u32

Returns the proof-of-work target spacing in seconds.

pub const fn target_timespan_seconds(self) -> u32

Returns the proof-of-work retarget timespan in seconds.

pub const fn allow_min_difficulty_blocks(self) -> bool

Returns whether non-retarget blocks may use the test-network minimum-difficulty rule.

pub const fn pow_no_retargeting(self) -> bool

Returns whether retarget heights keep the previous difficulty unchanged.

pub const fn enforce_bip94(self) -> bool

Returns whether retargeting uses the first block of the period as the base difficulty.

pub fn genesis_block_hash(self) -> Hash256

Returns the genesis block hash.

Trait Implementations

impl Clone for Network

fn clone(&self) -> Network

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Network

impl Debug for Network

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for Network

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Network

fn eq(&self, other: &Network) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
