Trait Implementations

impl Clone for EthereumHardfork

fn clone(&self) -> EthereumHardfork

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EthereumHardfork

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

Formats the value using the given formatter.

impl Default for EthereumHardfork

fn default() -> EthereumHardfork

Returns the “default value” for a type.

impl Display for EthereumHardfork

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

Formats the value using the given formatter.

impl FromStr for EthereumHardfork

type Err = ParseHardforkError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hardfork for EthereumHardfork

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

Fork name.

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

Returns boxed value.

impl Hash for EthereumHardfork

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,
