Implementations

impl SpecId

pub const NEXT: SpecId = Self::AMSTERDAM

The latest known spec. This may refer to a highly experimental hard fork that is not yet finalized or deployed on any network.

Warning: This value will change between minor versions as new hard forks are added. Do not rely on it for stable behavior.

pub const fn try_from_u8(spec_id: u8) -> Option<SpecId>

Returns the SpecId for the given u8.

pub const fn is_enabled_in(self, other: SpecId) -> bool

Returns true if the given specification ID is enabled in this spec.

Trait Implementations

impl Clone for SpecId

fn clone(&self) -> SpecId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpecId

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

Formats the value using the given formatter.

impl Default for SpecId

fn default() -> SpecId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SpecId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SpecId

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

Formats the value using the given formatter.

impl From<SpecId> for &'static str

fn from(spec_id: SpecId) -> &'static str

Converts to this type from the input type.

impl From<SpecId> for u8

fn from(spec_id: SpecId) -> u8

Converts to this type from the input type.

impl FromStr for SpecId

type Err = UnknownHardfork

The associated error which can be returned from parsing.

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

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

impl Hash for SpecId

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 SpecId

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

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

fn partial_cmp(&self, other: &SpecId) -> 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 SpecId

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 TryFrom<u8> for SpecId

type Error = u8

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<SpecId, <SpecId as TryFrom<u8>>::Error>

Performs the conversion.
