Struct BatchCommitment 

pub struct BatchCommitment {
    pub block_hash: H256,
    pub timestamp: u64,
    pub previous_batch: Digest,
    pub expiry: u8,
    pub chain_commitment: Option<ChainCommitment>,
    pub code_commitments: Vec<CodeCommitment>,
    pub validators_commitment: Option<ValidatorsCommitment>,
    pub rewards_commitment: Option<RewardsCommitment>,
}

Batch of different commitments that are created for a specific ethereum block.

Fields

block_hash: H256

timestamp: u64

Timestamp of ethereum block for which this batch has been created This timestamp is used to identify validator set to verify commitment (current or previous era)

previous_batch: Digest

Digest of the previous committed batch. This is used to verify that the batch is committed in the correct order.

expiry: u8

How long the batch is valid (in blocks since block_hash). if 1 - then valid only in child block if 2 - then valid in child and grandchild blocks … etc.

chain_commitment: Option<ChainCommitment>

code_commitments: Vec<CodeCommitment>

validators_commitment: Option<ValidatorsCommitment>

rewards_commitment: Option<RewardsCommitment>

impl Default for BatchCommitment

fn default() -> BatchCommitment

Returns the “default value” for a type.

impl Encode for BatchCommitment

fn size_hint(&self) -> usize

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

impl EncodeLike for BatchCommitment

impl Eq for BatchCommitment

impl PartialEq for BatchCommitment

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

Tests for self and other values to be equal, and is used by ==.

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

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