Struct Head

pub struct Head {
    pub number: u64,
    pub hash: FixedBytes<32>,
    pub difficulty: Uint<256, 4>,
    pub total_difficulty: Uint<256, 4>,
    pub timestamp: u64,
}

Describes the current head block.

The head block is the highest fully synced block.

Note: This is a slimmed down version of Header, primarily for communicating the highest block with the P2P network and the RPC.

Fields

number: u64

The number of the head block.

hash: FixedBytes<32>

The hash of the head block.

difficulty: Uint<256, 4>

The difficulty of the head block.

total_difficulty: Uint<256, 4>

The total difficulty at the head block.

timestamp: u64

The timestamp of the head block.

Implementations

impl Head

pub const fn new( number: u64, hash: FixedBytes<32>, difficulty: Uint<256, 4>, total_difficulty: Uint<256, 4>, timestamp: u64, ) -> Head

Creates a new Head instance.

pub fn update( &mut self, number: u64, hash: FixedBytes<32>, difficulty: Uint<256, 4>, total_difficulty: Uint<256, 4>, timestamp: u64, )

Updates the head block with new information.

pub fn is_empty(&self) -> bool

Checks if the head block is an empty block (i.e., has default values).

Trait Implementations

impl Clone for Head

fn clone(&self) -> Head

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Head

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

Formats the value using the given formatter.

impl Default for Head

fn default() -> Head

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Head

fn deserialize<__D>( __deserializer: __D, ) -> Result<Head, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Head

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

Formats the value using the given formatter.

impl Hash for Head

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 Ord for Head

fn cmp(&self, other: &Head) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Head

fn eq(&self, other: &Head) -> 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 PartialOrd for Head

fn partial_cmp(&self, other: &Head) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Head

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Head

impl Eq for Head

impl StructuralPartialEq for Head
