Struct icu::calendar::types::IsoHour

pub struct IsoHour(_);

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

Must be within inclusive bounds [0, 24].

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<IsoHour>

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<IsoHour>

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<(), Error>

Formats the value using the given formatter.

impl Default for IsoHour

fn default() -> IsoHour

Returns the “default value” for a type.

impl FromStr for IsoHour

type Err = CalendarError

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<IsoHour, <IsoHour as FromStr>::Err>

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

impl Hash for IsoHour

fn hash<__H>(&self, state: &mut __H) where
    __H: Hasher, 

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<IsoHour> for IsoHour

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &IsoHour) -> bool

This method tests for !=.

impl PartialOrd<IsoHour> 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

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.
