Struct ethereum_forkid::ForkFilter

pub struct ForkFilter { /* fields omitted */ }

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

#[must_use]pub const fn current(&self) -> ForkId

Return current fork id

pub fn validate(&self, fork_id: ForkId) -> Result<(), ValidationError>

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

Errors

Returns a ValidationError if the ForkId is not compatible.
