Enum icu::datetime::provider::pattern::TimeGranularity

#[non_exhaustive]
pub enum TimeGranularity {
    None,
    Hours,
    Minutes,
    Seconds,
    Nanoseconds,
}

The granularity of time represented in a Pattern. Ordered from least granular to most granular for comparison.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

No time is in the pattern.

Hours

Smallest time unit = hours.

Minutes

Smallest time unit = minutes.

Seconds

Smallest time unit = seconds.

Nanoseconds

Smallest time unit = nanoseconds.

Implementations

impl TimeGranularity

pub fn is_top_of_hour(self, minute: u8, second: u8, nanosecond: u32) -> bool

Returns true if the most granular time being displayed will align with the top of the hour, otherwise returns false. e.g. 12:00:00 is at the top of the hour for any display granularity. e.g. 12:00:05 is only at the top of the hour if the seconds are not displayed.

Trait Implementations

impl Bake for TimeGranularity

fn bake(&self, env: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl BakeSize for TimeGranularity

fn borrows_size(&self) -> usize

Returns the size

impl Clone for TimeGranularity

fn clone(&self) -> TimeGranularity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimeGranularity

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

Formats the value using the given formatter.

impl Default for TimeGranularity

fn default() -> TimeGranularity

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TimeGranularity

fn deserialize<__D>( __deserializer: __D, ) -> Result<TimeGranularity, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<PatternItem> for TimeGranularity

fn from(item: PatternItem) -> TimeGranularity

Retrieves the granularity of time represented by a PatternItem. If the PatternItem is not time-related, returns None.

impl Ord for TimeGranularity

fn cmp(&self, other: &TimeGranularity) -> 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 TimeGranularity

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

fn partial_cmp(&self, other: &TimeGranularity) -> 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 TimeGranularity

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> Yokeable<'a> for TimeGranularity

where TimeGranularity: Sized,

type Output = TimeGranularity

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&self) -> &<TimeGranularity as Yokeable<'a>>::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> <TimeGranularity as Yokeable<'a>>::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make( this: <TimeGranularity as Yokeable<'a>>::Output, ) -> TimeGranularity

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut <TimeGranularity as Yokeable<'a>>::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf> ZeroFrom<'zf, TimeGranularity> for TimeGranularity

fn zero_from(this: &'zf TimeGranularity) -> TimeGranularity

Clone the other C into a struct that may retain references into C.

impl Copy for TimeGranularity
