Struct freedom_dates::FreedomDate

pub struct FreedomDate { /* private fields */ }

A FreedomDate is the One True Date representation. All other models are Communist.

Implementations

impl FreedomDate

pub fn liberate(datestring: &str) -> Freesult

To liberate a representation of a date is to make it Free. But the FreeDate tree must occasionally be watered with the blood of badly-formed datestrings, and here is where the true test of Datriots is found.

Trait Implementations

impl Add<Duration> for FreedomDate

type Output = FreedomDate

The resulting type after applying the + operator.

fn add(self, rhs: Duration) -> Self::Output

Performs the + operation.

impl Clone for FreedomDate

fn clone(&self) -> FreedomDate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FreedomDate

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

Formats the value using the given formatter.

impl Default for FreedomDate

By default, FreedomDates are July 4th, ’76.

fn default() -> Self

Returns the “default value” for a type.

impl Display for FreedomDate

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

Formats the value using the given formatter.

impl FreedomTime for FreedomDate

fn freedomstamp(&self) -> u64

Number of whole seconds since the Birthday of Freedom.

impl From<u64> for FreedomDate

A FreedomDate that is value seconds after the Birthday of Freedom.

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Ord for FreedomDate

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<FreedomDate> for FreedomDate

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

impl PartialOrd<FreedomDate> for FreedomDate

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Sub<Duration> for FreedomDate

type Output = Result<FreedomDate, FreedomError>

The resulting type after applying the - operator.

fn sub(self, rhs: Duration) -> Self::Output

Performs the - operation.

impl Sub<FreedomDate> for FreedomDate

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.
