Struct ConsensusBranchId

pub struct ConsensusBranchId(/* private fields */);

The Consensus Branch Id, used to bind transactions and blocks to a particular network upgrade.

Implementations

impl ConsensusBranchId

pub const RPC_MISSING_ID: ConsensusBranchId

The value used by zcashd RPCs for missing consensus branch IDs.

Consensus

This value must only be used in RPCs.

The consensus rules handle missing branch IDs by rejecting blocks and transactions, so this substitute value must not be used in consensus-critical code.

pub fn current(network: &Network, height: Height) -> Option<ConsensusBranchId>

Returns the current consensus branch id for network and height.

Returns None if the network has no branch id at this height.

Trait Implementations

impl Clone for ConsensusBranchId

fn clone(&self) -> ConsensusBranchId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConsensusBranchId

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

Formats the value using the given formatter.

impl Default for ConsensusBranchId

fn default() -> ConsensusBranchId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ConsensusBranchId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ConsensusBranchId

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

Formats the value using the given formatter.

impl From<ConsensusBranchId> for u32

fn from(branch: ConsensusBranchId) -> u32

Converts to this type from the input type.

impl From<u32> for ConsensusBranchId

fn from(branch: u32) -> Self

Converts to this type from the input type.

impl FromHex for ConsensusBranchId

type Error = <[u8; 4] as FromHex>::Error

fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>

Creates an instance of type Self from the given hex string, or fails with a custom error type.

impl Hash for ConsensusBranchId

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

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 ConsensusBranchId

fn eq(&self, other: &ConsensusBranchId) -> 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.

impl Serialize for ConsensusBranchId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToHex for &ConsensusBranchId

fn encode_hex<T: FromIterator<char>>(&self) -> T

fn encode_hex_upper<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Upper case letters are used (e.g. F9B4CA)

impl ToHex for ConsensusBranchId

fn encode_hex<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Lower case letters are used (e.g. f9b4ca)

fn encode_hex_upper<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Upper case letters are used (e.g. F9B4CA)

impl TryFrom<ConsensusBranchId> for BranchId

type Error = Error

The type returned in the event of a conversion error.

fn try_from(id: ConsensusBranchId) -> Result<Self, Self::Error>

Performs the conversion.
