Enum BlockId

pub enum BlockId {
    Hash(RpcBlockHash),
    Number(BlockNumberOrTag),
}

A Block Identifier. https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1898.md

Variants

Hash(RpcBlockHash)

Trait Implementations

impl Clone for BlockId

fn clone(&self) -> BlockId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockId

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for BlockId

Available on crate feature serde only.

fn deserialize<D>( deserializer: D, ) -> Result<BlockId, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BlockId

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<(FixedBytes<32>, Option<bool>)> for BlockId

fn from(hash_can: (FixedBytes<32>, Option<bool>)) -> BlockId

Converts to this type from the input type.

impl From<BlockNumberOrTag> for BlockId

fn from(num: BlockNumberOrTag) -> BlockId

Converts to this type from the input type.

impl From<FixedBytes<32>> for BlockId

fn from(block_hash: FixedBytes<32>) -> BlockId

Converts to this type from the input type.

impl From<HashOrNumber> for BlockId

fn from(block: HashOrNumber) -> BlockId

Converts to this type from the input type.

impl From<RpcBlockHash> for BlockId

fn from(value: RpcBlockHash) -> BlockId

Converts to this type from the input type.

impl From<Uint<64, 1>> for BlockId

fn from(value: Uint<64, 1>) -> BlockId

type Err = ParseBlockIdError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<BlockId, <BlockId as FromStr>::Err>

impl PartialEq for BlockId

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