Generic trait over a set of ordered hardforks

Required Methods

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

where H: Hardfork,

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

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

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

fn fork_id(&self, head: &Head) -> ForkId

Compute the ForkId for the given Head following eip-6122 spec

fn latest_fork_id(&self) -> ForkId

Returns the ForkId for the last fork.

fn fork_filter(&self, head: Head) -> ForkFilter

Creates a ForkFilter for the block described by Head.

Provided Methods

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.

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
