Implementations

impl HashOrNumber

pub const fn as_number(self) -> Option<u64>

Returns the block number if it is a HashOrNumber::Number.

pub const fn as_hash(self) -> Option<FixedBytes<32>>

Returns the block hash if it is a HashOrNumber::Hash.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for HashOrNumber

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<HashOrNumber, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest( u: Unstructured<'arbitrary>, ) -> Result<HashOrNumber, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

impl Clone for HashOrNumber

fn clone(&self) -> HashOrNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HashOrNumber

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

Formats the value using the given formatter.

impl Decodable for HashOrNumber

Allows for RLP decoding of a hash or number

fn decode(buf: &mut &[u8]) -> Result<HashOrNumber, Error>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl<'de> Deserialize<'de> for HashOrNumber

fn deserialize<__D>( __deserializer: __D, ) -> Result<HashOrNumber, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for HashOrNumber

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

Formats the value using the given formatter.

impl Encodable for HashOrNumber

Allows for RLP encoding of either a hash or a number

fn encode(&self, out: &mut dyn BufMut)

Encodes the type into the out buffer.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl From<&FixedBytes<32>> for HashOrNumber

fn from(value: &FixedBytes<32>) -> HashOrNumber

Converts to this type from the input type.

impl From<FixedBytes<32>> for HashOrNumber

fn from(value: FixedBytes<32>) -> HashOrNumber

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 HashOrNumber

fn from(value: RpcBlockHash) -> HashOrNumber

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl From<u64> for HashOrNumber

fn from(value: u64) -> HashOrNumber

Converts to this type from the input type.

impl FromStr for HashOrNumber

type Err = ParseBlockHashOrNumberError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

impl Hash for HashOrNumber

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HashOrNumber

fn eq(&self, other: &HashOrNumber) -> 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.

impl Serialize for HashOrNumber

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for HashOrNumber

impl Eq for HashOrNumber

impl StructuralPartialEq for HashOrNumber
