Struct ChainHardforks 

pub struct ChainHardforks { /* private fields */ }

Ordered list of a chain hardforks that implement Hardfork.

Implementations

impl ChainHardforks

pub fn new(forks: Vec<(Box<dyn Hardfork>, ForkCondition)>) -> ChainHardforks

Creates a new ChainHardforks from a list which must be ordered by activation.

Equivalent Ethereum hardforks must be included as well.

pub fn len(&self) -> usize

Total number of hardforks.

pub fn is_empty(&self) -> bool

Checks if the fork list is empty.

pub fn fork<H>(&self, fork: H) -> ForkCondition

where H: Hardfork,

Retrieves ForkCondition from fork. If fork is not present, returns ForkCondition::Never.

pub fn get<H>(&self, fork: H) -> Option<ForkCondition>

where H: Hardfork,

Retrieves ForkCondition from fork if it exists, otherwise None.

pub fn fork_block<H>(&self, fork: H) -> Option<u64>

where H: Hardfork,

Retrieves the fork block number or timestamp from fork if it exists, otherwise None.

pub fn forks_iter( &self, ) -> impl Iterator<Item = (&(dyn Hardfork + 'static), ForkCondition)>

Get an iterator of all hardforks with their respective activation conditions.

pub fn last(&self) -> Option<(Box<dyn Hardfork>, ForkCondition)>

Get last hardfork from the list.

pub fn is_fork_active_at_timestamp<H>(&self, fork: H, timestamp: u64) -> bool

where H: Hardfork,

Convenience method to check if a fork is active at a given timestamp.

pub fn is_fork_active_at_block<H>(&self, fork: H, block_number: u64) -> bool

where H: Hardfork,

Convenience method to check if a fork is active at a given block number.

pub fn insert<H>(&mut self, fork: H, condition: ForkCondition)

where H: Hardfork,

Inserts fork into list, updating with a new ForkCondition if it already exists.

pub fn remove<H>(&mut self, fork: H)

where H: Hardfork,

Removes fork from list.

Trait Implementations

impl Clone for ChainHardforks

fn clone(&self) -> ChainHardforks

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainHardforks

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

Formats the value using the given formatter.

impl Default for ChainHardforks

fn default() -> ChainHardforks

Returns the “default value” for a type.

impl<T, const N: usize> From<[(T, ForkCondition); N]> for ChainHardforks

where T: Hardfork,

fn from(list: [(T, ForkCondition); N]) -> ChainHardforks

Converts to this type from the input type.

impl PartialEq for ChainHardforks

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

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.
