Implementations

impl BlockNumber

pub fn to_min_block_num(&self) -> Option<u64>

Convert block number to min block target.

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

Formats the value using the given formatter.

impl Default for BlockNumber

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Deserialize<'a> for BlockNumber

fn deserialize<D>(deserializer: D) -> Result<BlockNumber, D::Error>

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl Hash for BlockNumber

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

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::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<BlockNumber> for EpochNumber

type Error = Error

The type returned in the event of a conversion error.

fn try_from(x: BlockNumber) -> Result<EpochNumber, Error>

Performs the conversion.

impl Eq for BlockNumber

impl StructuralPartialEq for BlockNumber
