Enum common_types::ids::BlockId

pub enum BlockId {
    Hash(H256),
    Number(BlockNumber),
    Earliest,
    Latest,
}

Uniquely identifies block.

Variants

Hash(H256)

Block's sha3. Querying by hash is always faster.

Number(BlockNumber)

Block number within canon blockchain.

Earliest

Earliest block (genesis).

Latest

Latest mined block.
