Implementations

impl Time

pub const ZERO: Self

The zero time that can be represented by Time, i.e. 00:00:00.000000.

pub const MAX: Self

The max time that can be represented by Time, i.e. 23:59:59.999999.

pub const unsafe fn from_hms_unchecked(
    hour: u32,
    minute: u32,
    sec: u32,
    usec: u32
) -> Time

Creates a Time from the given hour, minute, second and microsecond.

Safety

This function is unsafe because the values are not checked for validity! Before using it, check that the values are all correct.

pub const fn try_from_hms(
    hour: u32,
    minute: u32,
    sec: u32,
    usec: u32
) -> Result<Time, Error>

Creates a Time from the given hour, minute, second and microsecond.

pub const fn is_valid(hour: u32, minute: u32, sec: u32, usec: u32) -> bool

Checks if the given hour, minute, second and microsecond fields are valid.

pub const fn usecs(self) -> i64

Gets the microseconds of Time.

pub const unsafe fn from_usecs_unchecked(usecs: i64) -> Self

Creates a Time from the given microseconds without checking validity.

Safety

This function is unsafe because the microsecond value is not checked for validity! Before using it, check that the value is correct.

pub const fn try_from_usecs(usecs: i64) -> Result<Self, Error>

Creates a Time from the given microseconds

pub const fn extract(self) -> (u32, u32, u32, u32)

Extracts (hour, minute, second, microsecond) from the time.

pub fn format<S: AsRef<str>>(self, fmt: S) -> Result<impl Display, Error>

Formats Time by given format string.

pub fn parse<S1: AsRef<str>, S2: AsRef<str>>(
    input: S1,
    fmt: S2
) -> Result<Self, Error>

Parses Time from given string and format.

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

Time subtracts Time

pub const fn add_interval_dt(self, interval: IntervalDT) -> Time

Time adds IntervalDT

pub const fn sub_interval_dt(self, interval: IntervalDT) -> Time

Time subtracts IntervalDT

pub fn mul_f64(self, number: f64) -> Result<IntervalDT, Error>

Time multiplies f64

pub fn div_f64(self, number: f64) -> Result<IntervalDT, Error>

‘Time’ divides f64
