Trait Implementations

impl Clone for BlockNumber

fn clone(&self) -> BlockNumber

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockNumber

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

Formats the value using the given formatter.

impl Default for BlockNumber

fn default() -> BlockNumber

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlockNumber

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BlockNumber

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

Formats the value using the given formatter.

impl From<LenientBlockNumber> for BlockNumber

fn from(b: LenientBlockNumber) -> BlockNumber

Converts to this type from the input type.

impl<T> From<T> for BlockNumber

where T: Into<U64>,

fn from(num: T) -> BlockNumber

Converts to this type from the input type.

impl FromStr for BlockNumber

type Err = String

The associated error which can be returned from parsing.

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

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

impl Hash for BlockNumber

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 BlockNumber

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BlockNumber

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 TryFrom<StringifiedBlockNumber> for BlockNumber

type Error = String

The type returned in the event of a conversion error.

fn try_from( value: StringifiedBlockNumber ) -> Result<BlockNumber, <BlockNumber as TryFrom<StringifiedBlockNumber>>::Error>

Performs the conversion.

impl Copy for BlockNumber

impl Eq for BlockNumber

impl StructuralPartialEq for BlockNumber
