Defines core blockchain settings per block.

Tailors unique settings for each network based on its genesis block.

Governs crucial blockchain behavior and adaptability.

Encapsulates parameters shaping network evolution and behavior.

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

Trait Implementations

impl Clone for ChainConfig

fn clone(&self) -> ChainConfig

Returns a copy 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

Formats the value using the given formatter.

impl Default for ChainConfig

fn default() -> Self

Returns the “default value” for a type.

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

where ChainConfig: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
