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.

) -> Result<Self, Error>

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

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

Creates a IntervalDT from the given microseconds without checking the validity.

Safety

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

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>
