Struct Time 

pub struct Time { /* private fields */ }

A time of day with optional UTC offset.

Stored as nanoseconds since midnight plus an optional UTC offset in seconds. Without an offset, this is a “local time.”

Examples

use grafeo_common::types::Time;

let t = Time::from_hms(14, 30, 0).unwrap();
assert_eq!(t.hour(), 14);
assert_eq!(t.minute(), 30);
assert_eq!(t.to_string(), "14:30:00");

let tz = t.with_offset(3600); // +01:00
assert_eq!(tz.to_string(), "14:30:00+01:00");

Implementations

impl Time

pub fn from_hms(hour: u32, min: u32, sec: u32) -> Option<Self>

Creates a time from hours (0-23), minutes (0-59), and seconds (0-59).

pub fn from_hms_nano(hour: u32, min: u32, sec: u32, nano: u32) -> Option<Self>

Creates a time from hours, minutes, seconds, and nanoseconds.

pub fn from_nanos(nanos: u64) -> Option<Self>

Creates a time from nanoseconds since midnight.

pub fn with_offset(self, offset_secs: i32) -> Self

Returns a new Time with the given UTC offset in seconds.

pub fn hour(&self) -> u32

Returns the hour component (0-23).

pub fn minute(&self) -> u32

Returns the minute component (0-59).

pub fn second(&self) -> u32

Returns the second component (0-59).

pub fn nanosecond(&self) -> u32

Returns the nanosecond component (0-999_999_999).

pub fn as_nanos(&self) -> u64

Returns the total nanoseconds since midnight.

pub fn offset_seconds(&self) -> Option<i32>

Returns the UTC offset in seconds, if present.

pub fn parse(s: &str) -> Option<Self>

Parses a time from ISO 8601 format HH:MM:SS[.nnn][+HH:MM|Z].

pub fn now() -> Self

Returns the current local time (UTC).

pub fn add_duration(self, dur: &Duration) -> Self

Adds a duration’s time component to this time.

Only the nanosecond component of the duration is used (months and days are not meaningful for time-of-day). The result wraps around at midnight.

Trait Implementations

impl Clone for Time

fn clone(&self) -> Time

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Time

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

Formats the value using the given formatter.

impl Default for Time

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Time

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Time

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

Formats the value using the given formatter.

impl From<Time> for Value

fn from(t: Time) -> Self

Converts to this type from the input type.

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Time

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

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

fn partial_cmp(&self, other: &Self) -> 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 Time

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
