Struct Epoch 

pub struct Epoch<Ts = u128>
where
    Ts: RawTimestamp,
{ /* private fields */ }

An Epoch represents a span of time defined by a starting Timestamp and a size in units of time (e.g., seconds, minutes, hours). The size indicates the duration of the epoch and is used to determine when the epoch ends.

Implementations

impl<Ts> Epoch<Ts>

where Ts: RawTimestamp,

pub const fn new(size: u128, timestamp: Ts) -> Self

returns a new instance of the Epoch using the given size and timestamp.

pub const fn size(&self) -> u128

The size of the epoch; epochs generally consider the number of steps, or size, (e.g. the number of seconds) that will need to be taken before the epoch is considered to be complete and a new one begins.

pub const fn timestamp(&self) -> &Timestamp<Ts>

returns an immutable reference to the timestamp

pub fn set_size(&mut self, size: u128)

update the size of the epoch

pub fn with_size(self, size: u128) -> Self

consumes the current instance to create another with the given size and current timestamp.

pub fn with_timestamp<U: RawTimestamp>(self, timestamp: U) -> Epoch<U>

consumes the current instance to create another with the given timestamp and current size.

Trait Implementations

where Ts: RawTimestamp + Clone,

fn clone(&self) -> Epoch<Ts>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Ts> Debug for Epoch<Ts>

where Ts: RawTimestamp + Debug,

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

Formats the value using the given formatter.

impl<'de, Ts> Deserialize<'de> for Epoch<Ts>

where Ts: RawTimestamp + Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Ts> Hash for Epoch<Ts>

where Ts: RawTimestamp + Hash,

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<Ts> Ord for Epoch<Ts>

where Ts: RawTimestamp + Ord,

fn cmp(&self, other: &Epoch<Ts>) -> 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,

Restrict a value to a certain interval.

impl<Ts> PartialEq for Epoch<Ts>

where Ts: RawTimestamp + PartialEq,

fn eq(&self, other: &Epoch<Ts>) -> 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.

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

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

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