Enum Hardfork 

#[non_exhaustive]
pub enum Hardfork {
    Frontier,
    Homestead,
    Byzantium,
    London,
    Shanghai,
    Cancun,
    Prague,
    Amsterdam,
}

Execution-layer hardfork identity used by explicit chain specs.

Variants (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.

Frontier

Frontier genesis rules.

Homestead

Homestead rules.

Byzantium

Byzantium rules.

London

London rules.

Shanghai

Shanghai rules.

Cancun

Cancun rules.

Prague

Prague/Pectra rules.

Amsterdam

Amsterdam rules.

Trait Implementations

impl Clone for Hardfork

fn clone(&self) -> Hardfork

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Hardfork

impl Debug for Hardfork

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

Formats the value using the given formatter.

impl Eq for Hardfork

impl Ord for Hardfork

fn cmp(&self, other: &Hardfork) -> 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 Hardfork

fn eq(&self, other: &Hardfork) -> 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 Hardfork

fn partial_cmp(&self, other: &Hardfork) -> 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.
