Struct TimeUnit 

pub struct TimeUnit { /* private fields */ }

Implementations

impl TimeUnit

pub fn name(&self) -> &'static str

このユニットの名前を返す。

pub fn is_convertible_to(&self, other: &Self) -> bool

この単位で表される値を、指定した単位に変換できるかどうかを検証する。 例えば、分単位はミリ秒単位に変換できるが、四半期単位は（一ヶ月の長さが毎月異なるため）日単位に変換できない。

param other 変換先単位 return 変換できる場合はtrue、そうでない場合はfalse

pub fn is_convertible_to_milliseconds(&self) -> bool

この単位で表される値を、ミリ秒単位に変換できるかどうかを検証する。 例えば、分単位はミリ秒単位に変換できるが、四半期単位は（一ヶ月の長さが毎月異なるため）ミリ秒単位に変換できない。

return 変換できる場合はtrue、そうでない場合はfalse

pub fn base_unit(&self) -> TimeUnit

この単位の計数の基数とすることができる最小の単位を取得する。 例えば、分単位はミリ秒単位で計数できるが、四半期単位は（一ヶ月の長さが毎月異なるため）月単位までしか計数できない。

return この単位の計数の基数とすることができる最小の単位

pub fn descending_units(&self) -> Vec<TimeUnit>

pub fn descending_units_for_display(&self) -> Vec<TimeUnit>

pub fn next_finer_unit(&self) -> Option<TimeUnit>

Trait Implementations

impl Clone for TimeUnit

fn clone(&self) -> TimeUnit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeUnit

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

Formats the value using the given formatter.

impl Hash for TimeUnit

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 TimeUnit

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

Restrict a value to a certain interval.

impl PartialEq for TimeUnit

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

fn partial_cmp(&self, other: &TimeUnit) -> 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 Eq for TimeUnit
