Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.

Size: 40 bytes

Size for each variant:

• Hash: 32 bytes
• Number: 15 bytes

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 copy 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<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.
