Enum icu_datetime::options::TimePrecision

#[non_exhaustive]
pub enum TimePrecision {
    HourPlus,
    HourExact,
    MinutePlus,
    MinuteExact,
    SecondPlus,
    SecondExact(FractionalSecondDigits),
}

A specification for how precisely to display the time of day.

The examples below are based on the following inputs and hour cycles:

1. 11 o’clock with 12-hour time
2. 16:20 (4:20 pm) with 24-hour time
3. 7:15:01.85 with 24-hour time

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.

HourPlus

Always display the hour. Display smaller fields if they are nonzero.

Examples:

1. 11 am
2. 16:20
3. 07:15:01.85

HourExact

Always display the hour. Hide all other time fields.

Examples:

1. 11 am
2. 16h
3. 07h

MinutePlus

Always display the hour and minute. Display the second if nonzero.

Examples:

1. 11:00 am
2. 16:20
3. 07:15:01.85

MinuteExact

Always display the hour and minute. Hide the second.

Examples:

1. 11:00 am
2. 16:20
3. 07:15

SecondPlus

Display the hour, minute, and second. Display fractional seconds if nonzero.

This is the default.

Examples:

1. 11:00:00 am
2. 16:20:00
3. 07:15:01.85

SecondExact(FractionalSecondDigits)

Display the hour, minute, and second with the given number of fractional second digits.

Examples with FractionalSecondDigits::F1:

1. 11:00:00.0 am
2. 16:20:00.0
3. 07:15:01.8

Trait Implementations

impl Clone for TimePrecision

fn clone(&self) -> TimePrecision

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimePrecision

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TimePrecision

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TimePrecision

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 IntoOption<TimePrecision> for TimePrecision

fn into_option(self) -> Option<Self>

Return self as an Option<T>

impl PartialEq for TimePrecision

fn eq(&self, other: &TimePrecision) -> 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 Serialize for TimePrecision

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TimePrecision

impl Eq for TimePrecision

impl StructuralPartialEq for TimePrecision
