Trait CompatibleDigestItem

pub trait CompatibleDigestItem: Sized {
    // Required methods
    fn babe_pre_digest(seal: PreDigest) -> Self;
    fn as_babe_pre_digest(&self) -> Option<PreDigest>;
    fn babe_seal(signature: Signature) -> Self;

}

A digest item which is usable with BABE consensus.

Required Methods

fn babe_pre_digest(seal: PreDigest) -> Self

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

fn as_babe_pre_digest(&self) -> Option<PreDigest>

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

fn babe_seal(signature: Signature) -> Self

Construct a digest item which contains a BABE seal.

fn as_babe_seal(&self) -> Option<Signature>

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

fn as_next_epoch_descriptor(&self) -> Option<NextEpochDescriptor>

If this item is a BABE epoch descriptor, return it.

fn as_next_config_descriptor(&self) -> Option<NextConfigDescriptor>

If this item is a BABE config descriptor, 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.
