Struct Epoch

pub struct Epoch(/* private fields */);

Granularity of updates.

For the purposes of this update mechanism, the updates cycle in blocks of 2^15 seconds, or about 9 hours.

Implementations

impl Epoch

pub fn current() -> Result<Epoch>

Returns the currently active Epoch.

pub fn try_from_unix(t: u64) -> Result<Self>

Returns the epoch for the given UNIX epoch.

pub fn pred(&self) -> Option<Epoch>

Returns the previous Epoch, if any.

pub fn succ(&self) -> Option<Epoch>

Returns the next Epoch, if any.

pub fn since(&self, other: Epoch) -> Result<impl Iterator<Item = Epoch>>

Returns an iterator over all epochs starting from this one to other, in descending order, excluding other.

pub fn serialize(&self, sink: &mut dyn Write) -> Result<()>

Writes the Epoch to the given io::Writer.

pub fn parse(source: &mut dyn Read) -> Result<Self>

Reads the Epoch from the given io::Reader.

type Output = Epoch

The resulting type after applying the + operator.

fn add(self, other: u32) -> Self

Performs the + operation.

impl Add for Epoch

type Output = Epoch

The resulting type after applying the + operator.

fn add(self, other: Epoch) -> Self

Performs the + operation.

impl Clone for Epoch

fn clone(&self) -> Epoch

Returns a duplicate of the value.

const 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 Display for Epoch

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

Formats the value using the given formatter.

impl From<u32> for Epoch

fn from(e: u32) -> Self

Converts to this type from the input type.

impl FromStr for Epoch

type Err = Error

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this 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 ==.

const 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.

type Output = Epoch

The resulting type after applying the - operator.

fn sub(self, other: u32) -> Self

Performs the - operation.

impl Sub for Epoch

type Output = Epoch

The resulting type after applying the - operator.

fn sub(self, other: Epoch) -> Self

Performs the - operation.

impl TryFrom<SystemTime> for Epoch

type Error = Error

The type returned in the event of a conversion error.

fn try_from(t: SystemTime) -> Result<Self>

Performs the conversion.

impl Copy for Epoch
