A digest item which is usable with Subspace consensus.

Required Methods

fn subspace_pre_digest<AccountId: Encode>( pre_digest: &PreDigest<AccountId>, ) -> Self

Construct a digest item which contains a Subspace pre-digest.

fn as_subspace_pre_digest<AccountId: Decode>( &self, ) -> Option<PreDigest<AccountId>>

If this item is an Subspace pre-digest, return it.

fn subspace_seal(signature: RewardSignature) -> Self

Construct a digest item which contains a Subspace seal.

fn as_subspace_seal(&self) -> Option<RewardSignature>

If this item is a Subspace signature, return the signature.

fn pot_slot_iterations(pot_slot_iterations: NonZeroU32) -> Self

Number of iterations for proof of time per slot, corresponds to slot that directly follows parent block’s slot and can change before slot for which block is produced

fn as_pot_slot_iterations(&self) -> Option<NonZeroU32>

If this item is a Subspace proof of time slot iterations, return it.

fn solution_range(solution_range: SolutionRange) -> Self

Construct a digest item which contains a solution range.

fn as_solution_range(&self) -> Option<SolutionRange>

If this item is a Subspace solution range, return it.

fn pot_parameters_change(pot_parameters_change: PotParametersChange) -> Self

Change of parameters to apply to PoT chain

fn as_pot_parameters_change(&self) -> Option<PotParametersChange>

If this item is a Subspace proof of time change of parameters, return it.

fn next_solution_range(solution_range: SolutionRange) -> Self

Construct a digest item which contains next solution range.

fn as_next_solution_range(&self) -> Option<SolutionRange>

If this item is a Subspace next solution range, return it.

fn segment_commitment( segment_index: SegmentIndex, segment_commitment: SegmentCommitment, ) -> Self

Construct a digest item which contains segment commitment.

fn as_segment_commitment(&self) -> Option<(SegmentIndex, SegmentCommitment)>

If this item is a Subspace segment commitment, return it.

fn enable_solution_range_adjustment_and_override( override_solution_range: Option<SolutionRange>, ) -> Self

Construct digest item than indicates enabling of solution range adjustment and override next solution range.

fn as_enable_solution_range_adjustment_and_override( &self, ) -> Option<Option<SolutionRange>>

If this item is a Subspace Enable solution range adjustment and override next solution range, return it.

fn root_plot_public_key_update(root_plot_public_key: Option<PublicKey>) -> Self

Construct digest item that indicates update of root plot public key.

fn as_root_plot_public_key_update(&self) -> Option<Option<PublicKey>>

If this item is a Subspace update of root plot public key, return it.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
