# Enum ethcore::client::BlockId [−] [src]

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

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.

`Pending`

Pending block.

## Trait Implementations

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
