Module reth::chainspec

Re-exported from reth_chainspec

Modules

• arbitrary
  The Arbitrary trait crate.

Macros

• hardfork
  Macro that defines different variants of a chain specific enum. See crate::Hardfork as an example.

Structs

• BaseFeeParams
  BaseFeeParams contains the config parameters that control block base fee computation
• Chain
  Either a known NamedChain or a EIP-155 chain ID.
• ChainHardforks
  Ordered list of a chain hardforks that implement Hardfork.
• ChainInfo
  Current status of the blockchain’s head.
• ChainSpec
  An Ethereum chain specification.
• ChainSpecBuilder
  A helper to build custom chain specs
• DepositContract
  PoS deposit contract details.
• DisplayHardforks
  A container for pretty-printing a list of hardforks.
• EnrForkIdEntry
  Represents a forward-compatible ENR entry for including the forkid in a node record via EIP-868. Forward compatibility is achieved via EIP-8.
• ForkBaseFeeParams
  A type alias to a vector of tuples of Hardfork and BaseFeeParams, sorted by Hardfork activation order. This is used to specify dynamic EIP-1559 parameters for chains like Optimism.
• ForkFilter
  Filter that describes the state of blockchain and can be used to check incoming ForkIds for compatibility.
• ForkHash
  CRC32 hash of all previous forks starting from genesis block.
• ForkId
  A fork identifier as defined by EIP-2124. Serves as the chain compatibility identifier.
• ForkTransition
  Represents a transition from one fork to another
• Head
  Describes the current head block.

Enums

• BaseFeeParamsKind
  A wrapper around BaseFeeParams that allows for specifying constant or dynamic EIP-1559 parameters based on the active Hardfork.
• ChainKind
  The kind of chain. Returned by Chain::kind. Prefer using Chain instead.
• EthereumHardfork
  The name of an Ethereum hardfork.
• ForkCondition
  The condition at which a fork is activated.
• ForkFilterKey
  How to filter forks.
• NamedChain
  An Ethereum EIP-155 chain.
• OptimismHardfork
  The name of an optimism hardfork.
• ValidationError
  Reason for rejecting provided ForkId.

Constants

• MIN_TRANSACTION_GAS
  Gas per transaction not creating a contract.

Statics

• DEV
  Dev testnet specification
• DEV_HARDFORKS
  Dev hardforks
• HOLESKY
  The Holesky spec
• MAINNET
  The Ethereum mainnet spec
• SEPOLIA
  The Sepolia spec

Traits

• ChainSpecProvider
  A trait for reading the current ChainSpec.
• EthChainSpec
  Trait representing type configuring a chain spec.
• EthereumHardforks
  Helper methods for Ethereum forks.
• Hardfork
  Generic hardfork trait.
• Hardforks
  Generic trait over a set of ordered hardforks
• OptimismHardforks
  Extends crate::EthereumHardforks with optimism helper methods.

Functions

• once_cell_set
  Simple utility to create a OnceCell with a value set.
• test_fork_idstest-utils
  Verifies ChainSpec configuration against expected data in given cases.
