Implementations

impl IntervalDT

pub const MIN: Self

pub const MAX: Self

The largest interval that can be represented by IntervalDT, i.e. 100000000 00:00:00.000000.

pub const ZERO: Self

The zero value of interval, i.e. 0 00:00:00.000000.

pub const unsafe fn from_dhms_unchecked(
    day: u32,
    hour: u32,
    minute: u32,
    sec: u32,
    usec: u32
) -> Self

Creates a IntervalDT from the given day, 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.

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

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

Safety

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

pub const fn usecs(self) -> i64

Gets the microseconds of IntervalDT.

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

Formats IntervalDT by given format string.

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

    self,
    interval: IntervalDT
) -> Result<IntervalDT, Error>

pub const fn sub_interval_dt(
    self,
    interval: IntervalDT
) -> Result<IntervalDT, Error>

IntervalDT subtracts IntervalDT

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

IntervalDT multiplies f64

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

IntervalDT divides f64

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