Implementations

impl HardFork

pub const fn from_version(version: u8) -> Result<HardFork, HardForkError>

Returns the hard-fork for a blocks BlockHeader::hardfork_version field.

ref: https://monero-book.cuprate.org/consensus_rules/hardforks.html#blocks-version-and-vote

Errors

Will return Err if the version is not a valid HardFork.

pub fn from_vote(vote: u8) -> HardFork

Returns the hard-fork for a blocks BlockHeader::hardfork_signal (vote) field.

https://monero-book.cuprate.org/consensus_rules/hardforks.html#blocks-version-and-vote

pub fn from_block_header( header: &BlockHeader, ) -> Result<(HardFork, HardFork), HardForkError>

Returns the HardFork version and vote from this block header.

Errors

Will return Err if the BlockHeader::hardfork_version is not a valid HardFork.

pub const fn as_u8(&self) -> u8

Returns the raw hard-fork value, as it would appear in BlockHeader::hardfork_version.

pub fn next_fork(&self) -> Option<HardFork>

Returns the next hard-fork.

pub const fn block_time(&self) -> Duration

Returns the target block time for this hardfork.

Trait Implementations

impl Arbitrary for HardFork

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = TupleUnion<((u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<TupleUnion<((u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>), (u32, Arc<fn() -> HardFork>))>>))>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _top: <HardFork as Arbitrary>::Parameters, ) -> <HardFork as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for HardFork

fn clone(&self) -> HardFork

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HardFork

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

Formats the value using the given formatter.

impl Default for HardFork

fn default() -> HardFork

Returns the “default value” for a type.

impl Hash for HardFork

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 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.

impl Copy for HardFork

impl Eq for HardFork

impl StructuralPartialEq for HardFork

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.
