Struct icu_calendar::types::IsoHour

pub struct IsoHour(u8);

An ISO-8601 hour component, for use with ISO calendars.

Must be within inclusive bounds [0, 24]. The value could be equal to 24 to denote the end of a day, with the writing 24:00:00. It corresponds to the same time as the next day at 00:00:00.

Tuple Fields

0: u8

Implementations

impl IsoHour

pub const fn number(self) -> u8

Gets the numeric value for this component.

pub const fn zero() -> IsoHour

Creates a new value at 0.

impl IsoHour

pub fn try_add(self, other: u8) -> Option<Self>

Attempts to add two values. Returns Some if the sum is within bounds. Returns None if the sum is out of bounds.

pub fn try_sub(self, other: u8) -> Option<Self>

Attempts to subtract two values. Returns Some if the difference is within bounds. Returns None if the difference is out of bounds.

Trait Implementations

impl Clone for IsoHour

fn clone(&self) -> IsoHour

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IsoHour

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

Formats the value using the given formatter.

impl Default for IsoHour

fn default() -> IsoHour

Returns the “default value” for a type.

impl From<IsoHour> for u8

fn from(input: IsoHour) -> Self

Converts to this type from the input type.

impl From<IsoHour> for usize

fn from(input: IsoHour) -> Self

Converts to this type from the input type.

impl FromStr for IsoHour

type Err = CalendarError

The associated error which can be returned from parsing.

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

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

impl Hash for IsoHour

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 Ord for IsoHour

fn cmp(&self, other: &IsoHour) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for IsoHour

fn eq(&self, other: &IsoHour) -> 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 IsoHour

fn partial_cmp(&self, other: &IsoHour) -> 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 TryFrom<u8> for IsoHour

type Error = CalendarError

The type returned in the event of a conversion error.

fn try_from(input: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<usize> for IsoHour

type Error = CalendarError

The type returned in the event of a conversion error.

fn try_from(input: usize) -> Result<Self, Self::Error>

Performs the conversion.
