Struct Epoch 

pub struct Epoch {
    seqnr: u64,
}

Represents a Yivi epoch by its sequence number. The 0th epoch starts at 1970-01-01T00:00:00Z and each epoch lasts exactly $60 \cdot 60 \cdot 24 \cdot 7$ seconds (= 1 week).

Fields

seqnr: u64

Implementations

impl Epoch

const MAX_SEQNR: u64

Largest valid sequence number: beyond it an epoch’s start falls outside the representable NumericDate range. From<NumericDate> never produces a larger one. The last valid epoch contains the maximal instant, so its end is unrepresentable and ends saturates there.

pub const fn seconds() -> u64

Length of a Yivi epoch in seconds.

pub fn current() -> Epoch

Returns the current Yivi epoch

pub fn with_seqnr(seqnr: u64) -> Result<Self, OutOfRange>

Returns the Yivi epoch with the given sequence number, or jwt::OutOfRange when it is so large that the epoch would fall outside the representable NumericDate range.

pub fn starts(&self) -> NumericDate

Returns the second this epoch starts

pub fn ends(&self) -> NumericDate

Returns the first second of the next epoch.

For the last representable epoch — whose successor would start after year 9999, never a real, present-day epoch — this saturates to the maximal representable instant rather than going out of range.

Trait Implementations

impl Clone for Epoch

fn clone(&self) -> Epoch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Epoch

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

Formats the value using the given formatter.

impl Default for Epoch

fn default() -> Epoch

Returns the “default value” for a type.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Epoch

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

Formats the value using the given formatter.

impl From<Epoch> for u64

fn from(epoch: Epoch) -> u64

Converts to this type from the input type.

impl From<NumericDate> for Epoch

fn from(nd: NumericDate) -> Self

Converts to this type from the input type.

impl Ord for Epoch

fn cmp(&self, other: &Epoch) -> 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 PartialEq for Epoch

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

impl PartialOrd for Epoch

fn partial_cmp(&self, other: &Epoch) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

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

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

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.

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 Epoch

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u64> for Epoch

type Error = OutOfRange

The type returned in the event of a conversion error.

fn try_from(seqnr: u64) -> Result<Self, Self::Error>

Performs the conversion.
