Conversion, hardfork scheduling, and trace metadata for a concrete execution spec.

Required Methods

fn evm_version_name(&self) -> String

fn from_foundry_hardfork(hardfork: FoundryHardfork) -> Option<Self>

Provided Methods

fn from_network_hardfork(_: &str) -> Option<Self>

fn historical_hardfork(chain_id: u64, timestamp: u64) -> Option<FoundryHardfork>

Returns this family’s hardfork at a historical source-chain timestamp. Unknown source chains return None; this never discovers another execution family.

fn fork_hardfork( chain_id: u64, timestamp: u64, endpoint_hardfork: Option<FoundryHardfork>, ) -> Option<FoundryHardfork>

Resolves a local fork’s hardfork from compatible endpoint metadata or its source schedule. Ethereum overrides this to retain the configured EVM version for local forks.

fn reported_hardfork(self) -> Option<FoundryHardfork>

Returns exact metadata for a directly selected spec, when the family requires it. Ethereum and Optimism retain their existing absence of metadata for direct spec overrides.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
