Struct Head

pub struct Head {
    pub number: BlockNumber,
    pub hash: B256,
    pub difficulty: U256,
    pub total_difficulty: U256,
    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: BlockNumber

The number of the head block.

hash: B256

The hash of the head block.

difficulty: U256

The difficulty of the head block.

total_difficulty: U256

The total difficulty at the head block.

timestamp: u64

The timestamp of the head block.

Implementations

impl Head

pub const fn new( number: BlockNumber, hash: B256, difficulty: U256, total_difficulty: U256, timestamp: u64, ) -> Self

Creates a new Head instance.

pub fn update( &mut self, number: BlockNumber, hash: B256, difficulty: U256, total_difficulty: U256, 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

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<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Head

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

Formats the value using the given formatter.

impl Hash for Head

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 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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Head

impl Eq for Head

impl StructuralPartialEq for Head

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
