Struct chain_time::era::TimeEra

pub struct TimeEra {
    epoch_start: Epoch,
    slot_start: Slot,
    slots_per_epoch: u32,
}

Describe a new era, which start at epoch_start and is associated to a specific slot. Each epoch have a constant number of slots on a given time era.

Fields

epoch_start: Epoch

slot_start: Slot

slots_per_epoch: u32

Implementations

impl TimeEra

pub fn new(slot_start: Slot, epoch_start: Epoch, slots_per_epoch: u32) -> Self

Set a new era to start on slot_start at epoch_start for a given slots per epoch.

pub fn epoch_start(&self) -> Epoch

retrieve the epoch start during a given Era

pub fn slot_start(&self) -> Slot

retrieve the slot start of an epoch during a given Era

pub fn slots_per_epoch(&self) -> u32

retrieve the number of slots in an epoch during a given Era

pub fn from_slot_to_era(&self, slot: Slot) -> Option<EpochPosition>

Try to return the epoch/inner-epoch-slot associated.

If the slot in parameter is before the beginning of this era, then None is returned.

pub fn from_era_to_slot(&self, pos: EpochPosition) -> Slot

Convert an epoch position into a flat slot

Trait Implementations

impl Arbitrary for TimeEra

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<TimeEra>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(args: <Self as Arbitrary>::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Arbitrary for TimeEra

fn arbitrary<G: Gen>(g: &mut G) -> Self

fn shrink(&self) -> Box<dyn Iterator<Item = Self>, Global>

impl Clone for TimeEra

fn clone(&self) -> TimeEra

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimeEra

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

Formats the value using the given formatter.

impl PartialEq<TimeEra> for TimeEra

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