Struct pgdatetime::Time

#[repr(transparent)]pub struct Time(_);

Time of day (no date).

Implementations

impl Time

pub const fn new() -> Self

Construct a Time value.

pub fn try_from_hms(h: i32, m: i32, s: f64) -> Result<Time, DateTimeError>

Constructs Time use hour, minute and second. second can indicate milliseconds an microseconds THe min unit is microseconds.

pub fn try_from_str(
    s: &str,
    type_mod: i32,
    date_order: DateOrder
) -> Result<Time, DateTimeError>

Parses Time string. type_mod should be 0 ~ 6, else will have no affect.

pub fn format(self, date_style: DateStyle) -> Result<String, DateTimeError>

Converts Time to string.

pub fn add_interval(self, span: Interval) -> Time

Time Adds Interval.

pub fn sub_time(self, time: Time) -> Interval

Time subtracts Time

pub fn sub_interval(self, span: Interval) -> Time

Time subtracts Interval.

Trait Implementations

impl Clone for Time

fn clone(&self) -> Time

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Time

impl DateTime for Time

fn date_part(
    &self,
    ty: FieldType,
    unit: DateUnit
) -> Result<Option<f64>, DateTimeError>

Extracts specified field from time type.

fn is_finite(&self) -> bool

Checks whether Time is finite.

fn truncate(&self, ty: FieldType, unit: DateUnit) -> Result<Self, DateTimeError>

Truncates Time to specified units.

fn is_infinite(&self) -> bool

Checks whether date time is infinite.

impl Debug for Time

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

Formats the value using the given formatter.

impl Eq for Time

impl From<Interval> for Time

Converts Interval to Time. This is defined as producing the fractional-day portion of the interval. Therefore, we can just ignore the months field. It is not real clear what to do with negative intervals, but we choose to subtract the floor, so that, say, '-2 hours' becomes '22:00:00'.

fn from(value: Interval) -> Self

Performs the conversion.

impl From<Time> for Interval

Converts Time to Interval.

fn from(value: Time) -> Self

Performs the conversion.

impl From<Time> for i64

Converts Time to i64 type.

fn from(t: Time) -> Self

Performs the conversion.

impl From<i64> for Time

Converts i64 to Date to type.

fn from(v: i64) -> Self

Performs the conversion.

impl Hash for Time

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for Time

fn cmp(&self, other: &Time) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Time> for Time

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

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

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

This method tests for !=.

impl PartialOrd<Time> for Time

fn partial_cmp(&self, other: &Time) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Time) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Time) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Time) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Time) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
