impl Arbitrary for EpochState

§

type Parameters = (<u64 as Arbitrary>::Parameters, <ValidatorVerifier as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.
§

type Strategy = Map<(<u64 as Arbitrary>::Strategy, <ValidatorVerifier as Arbitrary>::Strategy), fn(_: (u64, ValidatorVerifier)) -> EpochState>

The type of Strategy used to generate values of type Self.
source§

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

impl PartialEq<EpochState> for EpochState

source§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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

source§

fn epoch_change_verification_required(&self, epoch: u64) -> bool

Returns true in case the given epoch is larger than the existing verifier can support. In this case the EpochChangeProof should be verified and the verifier updated.
source§
