Expand description

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

Required Methods§

Source

fn evm_version_name(&self) -> String

Source

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

Provided Methods§

Source

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

Source

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.

Source

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.

Source

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.
