Represents a node’s chain configuration.

See geth’s ChainConfig struct for the source of each field.

Fields

chain_id: u64

The network’s chain ID.

homestead_block: Option<u64>

The homestead switch block (None = no fork, 0 = already homestead).

dao_fork_block: Option<u64>

The DAO fork switch block (None = no fork).

dao_fork_support: bool

Whether or not the node supports the DAO hard-fork.

eip150_block: Option<u64>

The EIP-150 hard fork block (None = no fork).

eip150_hash: Option<H256>

The EIP-150 hard fork hash.

eip155_block: Option<u64>

The EIP-155 hard fork block.

eip158_block: Option<u64>

The EIP-158 hard fork block.

byzantium_block: Option<u64>

The Byzantium hard fork block.

constantinople_block: Option<u64>

The Constantinople hard fork block.

petersburg_block: Option<u64>

The Petersburg hard fork block.

istanbul_block: Option<u64>

The Istanbul hard fork block.

muir_glacier_block: Option<u64>

The Muir Glacier hard fork block.

berlin_block: Option<u64>

The Berlin hard fork block.

london_block: Option<u64>

The London hard fork block.

arrow_glacier_block: Option<u64>

The Arrow Glacier hard fork block.

gray_glacier_block: Option<u64>

The Gray Glacier hard fork block.

merge_netsplit_block: Option<u64>

Virtual fork after the merge to use as a network splitter.

shanghai_time: Option<u64>

Shanghai switch time.

cancun_time: Option<u64>

Cancun switch time.

terminal_total_difficulty: Option<U256>

Total difficulty reached that triggers the merge consensus upgrade.

terminal_total_difficulty_passed: bool

A flag specifying that the network already passed the terminal total difficulty. Its purpose is to disable legacy sync without having seen the TTD locally.

ethash: Option<EthashConfig>

Ethash parameters.

clique: Option<CliqueConfig>

Clique parameters.

Trait Implementations

impl Clone for ChainConfig

fn clone(&self) -> ChainConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChainConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ChainConfig

fn default() -> ChainConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChainConfig

where ChainConfig: Default,

fn deserialize<__D>( __deserializer: __D, ) -> Result<ChainConfig, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChainConfig

fn eq(&self, other: &ChainConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ChainConfig

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ChainConfig

impl StructuralPartialEq for ChainConfig
