Implementations

impl HardForkConfig

pub fn complete_mainnet(&self) -> Result<HardForkSwitch, String>

If all parameters which have been set are correct for mainnet, then sets all None to default values, otherwise, return an Err.

pub fn complete_testnet(&self) -> Result<HardForkSwitch, String>

If all parameters which have been set are correct for testnet, then sets all None to default values, otherwise, return an Err.

pub fn complete_with_default(
    &self,
    default: EpochNumber
) -> Result<HardForkSwitch, String>

Converts to a hard fork switch.

Enable features which are set to None at the user provided epoch.
