Struct exonum::blockchain::BlockParams

pub struct BlockParams<'a> { /* fields omitted */ }

Block metadata provided to BlockchainMut::create_patch by the consensus algorithm.

Some data regarding blocks is not known in advance, for example, the ID of the validator that has proposed the block, or the block contents. Thus, this data needs to be supplied to BlockchainMut externally from the consensus algorithm implementation. The standard implementation is located in the exonum-node crate.

Methods

impl<'a> BlockParams<'a>

pub fn new(proposer: ValidatorId, epoch: Height, tx_hashes: &'a [Hash]) -> Self

Creates a new BlockParams instance for a normal block.

pub fn skip(proposer: ValidatorId, epoch: Height) -> Self

Creates a new BlockParams instance for a block skip.

pub fn with_contents(
    contents: BlockContents<'a>,
    proposer: ValidatorId,
    epoch: Height
) -> Self

Creates BlockParams with the provided contents.
