Re-export for convenience The name of an optimism hardfork.

When building a list of hardforks for a chain, it’s still expected to zip with [EthereumHardfork].

Implementations

impl OpHardfork

pub const VARIANTS: &'static [OpHardfork]

All hardfork variants

pub const fn name(&self) -> &'static str

Returns variant as str.

impl OpHardfork

pub const fn base_sepolia() -> [(OpHardfork, ForkCondition); 8]

Base Sepolia list of hardforks.

pub const fn idx(&self) -> usize

Returns index of self in sorted canonical array.

Trait Implementations

impl Clone for OpHardfork

fn clone(&self) -> OpHardfork

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpHardfork

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

Formats the value using the given formatter.

impl Default for OpHardfork

fn default() -> OpHardfork

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OpHardfork

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OpHardfork

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

Formats the value using the given formatter.

impl FromStr for OpHardfork

type Err = ParseHardforkError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<OpHardfork, <OpHardfork as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hardfork for OpHardfork

fn name(&self) -> &'static str

Fork name.

fn boxed(&self) -> Box<dyn Hardfork + '_>

Returns boxed value.

impl Hash for OpHardfork

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 OpHardfork

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

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

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 OpHardfork

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 OpHardfork

impl Eq for OpHardfork

impl StructuralPartialEq for OpHardfork

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.
