Struct ForkFilter

Source 
pub struct ForkFilter { /* private fields */ }
Expand description

Re-exported EIP-2124 forkid types. Filter that describes the state of blockchain and can be used to check incoming ForkIds for compatibility.

Implementations§

Source§

impl ForkFilter

Source

pub fn new<F>( head: Head, genesis_hash: FixedBytes<32>, genesis_timestamp: u64, forks: F, ) -> ForkFilter
where F: IntoIterator<Item = ForkFilterKey>,

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

Source

pub fn set_head(&mut self, head: Head) -> Option<ForkTransition>

Set the current head.

If the update updates the current ForkId it returns a ForkTransition

Source

pub const fn current(&self) -> ForkId

Return current fork id

Source

pub fn set_current_fork_id(&mut self, fork_id: ForkId)

Manually set the current fork id.

Caution: this disregards all configured fork filters and is reset on the next head update. This is useful for testing or to connect to networks over p2p where only the latest forkid is known.

Source

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

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

Implements the rules following: https://github.com/ethereum/EIPs/blob/master/EIPS/eip-2124.md#stale-software-examples

§Errors

Returns a ValidationError if the ForkId is not compatible.
