Struct Time 

#[repr(transparent)]
pub struct Time(pub i64);

Represents a time of day with nanosecond precision.

This struct is a wrapper around an i64 value representing the number of nanoseconds since midnight. It provides various methods for creating, manipulating, and converting time values.

Tuple Fields

0: i64

Implementations

impl Time

pub const fn from_i64(nanos: i64) -> Self

Creates a new Time instance from the given number of nanoseconds.

pub const fn is_nat(&self) -> bool

Checks if the time is “not a time” (NAT).

Returns true if the internal value is i64::MIN, which represents an invalid time.

pub const fn is_not_nat(&self) -> bool

Checks if the time is a valid time (not NAT).

Returns true if the internal value is not i64::MIN.

pub const fn nat() -> Self

Returns a Time instance representing “not a time” (NAT).

pub const fn into_i64(self) -> i64

Converts the Time instance to its raw i64 value.

pub fn from_cr(cr: &NaiveTime) -> Self

Creates a Time instance from a chrono::NaiveTime.

pub const fn as_cr(&self) -> Option<NaiveTime>

Converts the Time instance to a chrono::NaiveTime, if valid.

pub const fn from_hms(hour: i64, min: i64, sec: i64) -> Self

Creates a Time instance from hours, minutes, and seconds.

pub const fn from_hms_milli(hour: i64, min: i64, sec: i64, milli: i64) -> Self

Creates a Time instance from hours, minutes, seconds, and milliseconds.

pub const fn from_hms_micro(hour: i64, min: i64, sec: i64, micro: i64) -> Self

Creates a Time instance from hours, minutes, seconds, and microseconds.

pub const fn from_hms_nano(hour: i64, min: i64, sec: i64, nano: i64) -> Self

Creates a Time instance from hours, minutes, seconds, and nanoseconds.

pub const fn from_num_seconds_from_midnight(secs: i64, nano: i64) -> Self

Creates a Time instance from the number of seconds since midnight and additional nanoseconds.

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

Parses a string into a Time instance using an optional format string.

If no format is provided, it attempts to parse using the default format.

Trait Implementations

impl Add<TimeDelta> for Time

type Output = Time

The resulting type after applying the + operator.

fn add(self, rhs: TimeDelta) -> Self::Output

Performs the + operation.

impl Default for Time

fn default() -> Time

Returns the “default value” for a type.

impl Display for Time

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

Formats the value using the given formatter.

impl From<Option<i64>> for Time

fn from(value: Option<i64>) -> Self

Converts to this type from the input type.

impl From<i64> for Time

fn from(value: i64) -> Self

Converts to this type from the input type.

impl FromStr for Time

type Err = TError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> TResult<Self>

Parses a string s to return a value of this type.

impl Hash for Time

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: &Time) -> 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: &Time) -> 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 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.

type Output = Time

The resulting type after applying the - operator.

fn sub(self, rhs: TimeDelta) -> Self::Output
