Struct ethereum_forkid::ForkFilter

pub struct ForkFilter { /* private fields */ }

Filter that describes the state of blockchain and can be used to check incoming ForkIds for compatibility.

Implementations

impl ForkFilter

pub fn new<F>(head: BlockNumber, genesis: H256, forks: F) -> Self where
    F: IntoIterator<Item = BlockNumber>, 

Create the filter from provided head, genesis block hash, past forks and expected future forks.

pub fn set_head(&mut self, head: BlockNumber)

Set the current head

pub const fn current(&self) -> ForkId

Return current fork id

pub fn is_compatible(&self, fork_id: ForkId) -> Result<(), RejectReason>

Check whether the provided ForkId is compatible based on the validation rules in EIP-2124.

Errors

Returns a RejectReason if the ForkId is not compatible.

Trait Implementations

impl Clone for ForkFilter

fn clone(&self) -> ForkFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ForkFilter

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

Formats the value using the given formatter.

impl MallocSizeOf for ForkFilter

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself. If T::size_of is a constant, consider implementing constant_size as well.

fn constant_size() -> Option<usize>

Used to optimize MallocSizeOf implementation for collections like Vec and HashMap to avoid iterating over them unnecessarily. The Self: Sized bound is for object safety.

impl PartialEq<ForkFilter> for ForkFilter

fn eq(&self, other: &ForkFilter) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ForkFilter) -> bool

This method tests for !=.
