Struct sp_beefy::mmr::BeefyAuthoritySet

pub struct BeefyAuthoritySet<MerkleRoot> {
    pub id: ValidatorSetId,
    pub len: u32,
    pub root: MerkleRoot,
}

Details of a BEEFY authority set.

Fields

id: ValidatorSetId

Id of the set.

Id is required to correlate BEEFY signed commitments with the validator set. Light Client can easily verify that the commitment witness it is getting is produced by the latest validator set.

len: u32

Number of validators in the set.

Some BEEFY Light Clients may use an interactive protocol to verify only a subset of signatures. We put set length here, so that these clients can verify the minimal number of required signatures.

root: MerkleRoot

Merkle Root Hash built from BEEFY AuthorityIds.

This is used by Light Clients to confirm that the commitments are signed by the correct validator set. Light Clients using interactive protocol, might verify only subset of signatures, hence don’t require the full list here (will receive inclusion proofs).

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<MerkleRoot: Default> Default for BeefyAuthoritySet<MerkleRoot>

fn default() -> BeefyAuthoritySet<MerkleRoot>

Returns the “default value” for a type.

impl<'de, MerkleRoot> Deserialize<'de> for BeefyAuthoritySet<MerkleRoot>where MerkleRoot: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<MerkleRoot> Encode for BeefyAuthoritySet<MerkleRoot>where MerkleRoot: Encode,

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<MerkleRoot> MaxEncodedLen for BeefyAuthoritySet<MerkleRoot>where MerkleRoot: MaxEncodedLen,

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl<MerkleRoot: PartialEq> PartialEq<BeefyAuthoritySet<MerkleRoot>> for BeefyAuthoritySet<MerkleRoot>

fn eq(&self, other: &BeefyAuthoritySet<MerkleRoot>) -> bool

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