Struct EpochId

pub struct EpochId(pub CryptoHash);

Epoch identifier – wrapped hash, to make it easier to distinguish. EpochId of epoch T is the hash of last block in T-2 EpochId of first two epochs is 0

Tuple Fields

0: CryptoHash

Trait Implementations

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for EpochId

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for EpochId

fn clone(&self) -> EpochId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpochId

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

Formats the value using the given formatter.

impl Default for EpochId

fn default() -> EpochId

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EpochId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for EpochId

fn from_str(epoch_id_str: &str) -> Result<Self, Self::Err>

Decodes base58-encoded string into a 32-byte crypto hash.

type Err = Box<dyn Error + Sync + Send>

The associated error which can be returned from parsing.

impl Hash for EpochId

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 Ord for EpochId

fn cmp(&self, other: &EpochId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for EpochId

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for EpochId

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

where __S: Serializer,
