Trait deltalake::datafusion::prelude::Sub

pub trait Sub<Rhs = Self> {
    type Output;

    // Required method
    fn sub(self, rhs: Rhs) -> Self::Output;
}

The subtraction operator -.

Note that Rhs is Self by default, but this is not mandatory. For example, std::time::SystemTime implements Sub<Duration>, which permits operations of the form SystemTime = SystemTime - Duration.

Examples

Subtractable points

use std::ops::Sub;

#[derive(Debug, Copy, Clone, PartialEq)]
struct Point {
    x: i32,
    y: i32,
}

impl Sub for Point {
    type Output = Self;

    fn sub(self, other: Self) -> Self::Output {
        Self {
            x: self.x - other.x,
            y: self.y - other.y,
        }
    }
}

assert_eq!(Point { x: 3, y: 3 } - Point { x: 2, y: 3 },
           Point { x: 1, y: 0 });

Implementing Sub with generics

Here is an example of the same Point struct implementing the Sub trait using generics.

use std::ops::Sub;

#[derive(Debug, PartialEq)]
struct Point<T> {
    x: T,
    y: T,
}

// Notice that the implementation uses the associated type `Output`.
impl<T: Sub<Output = T>> Sub for Point<T> {
    type Output = Self;

    fn sub(self, other: Self) -> Self::Output {
        Point {
            x: self.x - other.x,
            y: self.y - other.y,
        }
    }
}

assert_eq!(Point { x: 2, y: 3 } - Point { x: 1, y: 0 },
           Point { x: 1, y: 3 });

Required Associated Types

type Output

impl Sub for NaiveDate

Subtracts another NaiveDate from the current date. Returns a TimeDelta of integral numbers.

This does not overflow or underflow at all, as all possible output fits in the range of TimeDelta.

The implementation is a wrapper around NaiveDate::signed_duration_since.

Example

use chrono::{NaiveDate, TimeDelta};

let from_ymd = |y, m, d| NaiveDate::from_ymd_opt(y, m, d).unwrap();

assert_eq!(from_ymd(2014, 1, 1) - from_ymd(2014, 1, 1), TimeDelta::zero());
assert_eq!(from_ymd(2014, 1, 1) - from_ymd(2013, 12, 31), TimeDelta::try_days(1).unwrap());
assert_eq!(from_ymd(2014, 1, 1) - from_ymd(2014, 1, 2), TimeDelta::try_days(-1).unwrap());
assert_eq!(from_ymd(2014, 1, 1) - from_ymd(2013, 9, 23), TimeDelta::try_days(100).unwrap());
assert_eq!(from_ymd(2014, 1, 1) - from_ymd(2013, 1, 1), TimeDelta::try_days(365).unwrap());
assert_eq!(
    from_ymd(2014, 1, 1) - from_ymd(2010, 1, 1),
    TimeDelta::try_days(365 * 4 + 1).unwrap()
);
assert_eq!(
    from_ymd(2014, 1, 1) - from_ymd(1614, 1, 1),
    TimeDelta::try_days(365 * 400 + 97).unwrap()
);

type Output = TimeDelta

impl Sub for NaiveDateTime

Subtracts another NaiveDateTime from the current date and time. This does not overflow or underflow at all.

As a part of Chrono’s leap second handling, the subtraction assumes that there is no leap second ever, except when any of the NaiveDateTimes themselves represents a leap second in which case the assumption becomes that there are exactly one (or two) leap second(s) ever.

The implementation is a wrapper around NaiveDateTime::signed_duration_since.

Example

use chrono::{NaiveDate, TimeDelta};

let from_ymd = |y, m, d| NaiveDate::from_ymd_opt(y, m, d).unwrap();

let d = from_ymd(2016, 7, 8);
assert_eq!(
    d.and_hms_opt(3, 5, 7).unwrap() - d.and_hms_opt(2, 4, 6).unwrap(),
    TimeDelta::try_seconds(3600 + 60 + 1).unwrap()
);

// July 8 is 190th day in the year 2016
let d0 = from_ymd(2016, 1, 1);
assert_eq!(
    d.and_hms_milli_opt(0, 7, 6, 500).unwrap() - d0.and_hms_opt(0, 0, 0).unwrap(),
    TimeDelta::try_seconds(189 * 86_400 + 7 * 60 + 6).unwrap()
        + TimeDelta::try_milliseconds(500).unwrap()
);

Leap seconds are handled, but the subtraction assumes that no other leap seconds happened.

let leap = from_ymd(2015, 6, 30).and_hms_milli_opt(23, 59, 59, 1_500).unwrap();
assert_eq!(
    leap - from_ymd(2015, 6, 30).and_hms_opt(23, 0, 0).unwrap(),
    TimeDelta::try_seconds(3600).unwrap() + TimeDelta::try_milliseconds(500).unwrap()
);
assert_eq!(
    from_ymd(2015, 7, 1).and_hms_opt(1, 0, 0).unwrap() - leap,
    TimeDelta::try_seconds(3600).unwrap() - TimeDelta::try_milliseconds(500).unwrap()
);

type Output = TimeDelta

impl Sub for NaiveTime

Subtracts another NaiveTime from the current time. Returns a TimeDelta within +/- 1 day. This does not overflow or underflow at all.

As a part of Chrono’s leap second handling, the subtraction assumes that there is no leap second ever, except when any of the NaiveTimes themselves represents a leap second in which case the assumption becomes that there are exactly one (or two) leap second(s) ever.

The implementation is a wrapper around NaiveTime::signed_duration_since.

Example

use chrono::{NaiveTime, TimeDelta};

let from_hmsm = |h, m, s, milli| NaiveTime::from_hms_milli_opt(h, m, s, milli).unwrap();

assert_eq!(from_hmsm(3, 5, 7, 900) - from_hmsm(3, 5, 7, 900), TimeDelta::zero());
assert_eq!(
    from_hmsm(3, 5, 7, 900) - from_hmsm(3, 5, 7, 875),
    TimeDelta::try_milliseconds(25).unwrap()
);
assert_eq!(
    from_hmsm(3, 5, 7, 900) - from_hmsm(3, 5, 6, 925),
    TimeDelta::try_milliseconds(975).unwrap()
);
assert_eq!(
    from_hmsm(3, 5, 7, 900) - from_hmsm(3, 5, 0, 900),
    TimeDelta::try_seconds(7).unwrap()
);
assert_eq!(
    from_hmsm(3, 5, 7, 900) - from_hmsm(3, 0, 7, 900),
    TimeDelta::try_seconds(5 * 60).unwrap()
);
assert_eq!(
    from_hmsm(3, 5, 7, 900) - from_hmsm(0, 5, 7, 900),
    TimeDelta::try_seconds(3 * 3600).unwrap()
);
assert_eq!(
    from_hmsm(3, 5, 7, 900) - from_hmsm(4, 5, 7, 900),
    TimeDelta::try_seconds(-3600).unwrap()
);
assert_eq!(
    from_hmsm(3, 5, 7, 900) - from_hmsm(2, 4, 6, 800),
    TimeDelta::try_seconds(3600 + 60 + 1).unwrap() + TimeDelta::try_milliseconds(100).unwrap()
);

Leap seconds are handled, but the subtraction assumes that there were no other leap seconds happened.

assert_eq!(from_hmsm(3, 0, 59, 1_000) - from_hmsm(3, 0, 59, 0), TimeDelta::try_seconds(1).unwrap());
assert_eq!(from_hmsm(3, 0, 59, 1_500) - from_hmsm(3, 0, 59, 0),
           TimeDelta::try_milliseconds(1500).unwrap());
assert_eq!(from_hmsm(3, 0, 59, 1_000) - from_hmsm(3, 0, 0, 0), TimeDelta::try_seconds(60).unwrap());

impl Sub<Duration> for std::time::Instant

type Output = Instant

impl Sub<Duration> for SystemTime

type Output = SystemTime

impl Sub<Duration> for NaiveDateTime

Subtract std::time::Duration from NaiveDateTime.

As a part of Chrono’s [leap second handling] the subtraction assumes that there is no leap second ever, except when the NaiveDateTime itself represents a leap second in which case the assumption becomes that there is exactly a single leap second ever.

Panics

Panics if the resulting date would be out of range. Consider using NaiveDateTime::checked_sub_signed to get an Option instead.

type Output = NaiveDateTime

impl Sub<Duration> for NaiveTime

Subtract std::time::Duration from NaiveTime.

This wraps around and never overflows or underflows. In particular the subtraction ignores integral number of days.

impl Sub<Months> for NaiveDate

Subtract Months from NaiveDate.

The result will be clamped to valid days in the resulting month, see checked_sub_months for details.

Panics

Panics if the resulting date would be out of range. Consider using NaiveDate::checked_sub_months to get an Option instead.

Example

use chrono::{Months, NaiveDate};

let from_ymd = |y, m, d| NaiveDate::from_ymd_opt(y, m, d).unwrap();

assert_eq!(from_ymd(2014, 1, 1) - Months::new(11), from_ymd(2013, 2, 1));
assert_eq!(from_ymd(2014, 1, 1) - Months::new(12), from_ymd(2013, 1, 1));

assert_eq!(
    NaiveDate::from_ymd_opt(2014, 01, 01).unwrap().and_hms_opt(01, 00, 00).unwrap()

Subtract FixedOffset from NaiveTime.

This wraps around and never overflows or underflows. In particular the subtraction ignores integral number of days.

type Output = NaiveTime

impl Sub<TimeDelta> for NaiveDate

Subtract TimeDelta from NaiveDate.

This discards the fractional days in TimeDelta, rounding to the closest integral number of days towards TimeDelta::zero(). It is the same as the addition with a negated TimeDelta.

Panics

Panics if the resulting date would be out of range. Consider using NaiveDate::checked_sub_signed to get an Option instead.

Example

use chrono::{NaiveDate, TimeDelta};

let from_ymd = |y, m, d| NaiveDate::from_ymd_opt(y, m, d).unwrap();

);
assert_eq!(

);

let d = from_ymd(2016, 7, 8);

assert_eq!(hms(3, 5, 7) - TimeDelta::zero(), hms(3, 5, 7));

assert_eq!(hms(3, 5, 7) - TimeDelta::try_seconds(-1).unwrap(), hms(3, 5, 8));
assert_eq!(hms(3, 5, 7) - TimeDelta::try_seconds(3600 + 60).unwrap(), hms(2, 4, 7));
assert_eq!(

);

let hmsm = |h, m, s, milli| d.and_hms_milli_opt(h, m, s, milli).unwrap();
assert_eq!(hmsm(3, 5, 7, 450) - TimeDelta::try_milliseconds(670).unwrap(), hmsm(3, 5, 6, 780));

Leap seconds are handled, but the subtraction assumes that it is the only leap second happened.

let leap = hmsm(3, 5, 59, 1_300);
assert_eq!(leap - TimeDelta::zero(), hmsm(3, 5, 59, 1_300));

impl<Tz> Sub<Duration> for DateTime<Tz>

where Tz: TimeZone,

Subtract std::time::Duration from DateTime.

As a part of Chrono’s [leap second handling] the subtraction assumes that there is no leap second ever, except when the DateTime itself represents a leap second in which case the assumption becomes that there is exactly a single leap second ever.

Panics

Panics if the resulting date would be out of range. Consider using DateTime<Tz>::checked_sub_signed to get an Option instead.

type Output = DateTime<Tz>

impl<Tz> Sub<Months> for DateTime<Tz>

where Tz: TimeZone,

Subtract Months from DateTime.

The result will be clamped to valid days in the resulting month, see DateTime<Tz>::checked_sub_months for details.

Panics

Panics if:

• The resulting date would be out of range.
• The local time at the resulting date does not exist or is ambiguous, for example during a daylight saving time transition.

Strongly consider using DateTime<Tz>::checked_sub_months to get an Option instead.

type Output = DateTime<Tz>

impl<Tz> Sub<Days> for DateTime<Tz>

where Tz: TimeZone,

Subtract Days from DateTime.

Panics

Panics if:

• The resulting date would be out of range.
• The local time at the resulting date does not exist or is ambiguous, for example during a daylight saving time transition.

Strongly consider using DateTime<Tz>::checked_sub_days to get an Option instead.

type Output = DateTime<Tz>

impl<Tz> Sub<FixedOffset> for DateTime<Tz>

impl<Tz> Sub<TimeDelta> for chrono::date::Date<Tz>

where Tz: TimeZone,

type Output = Date<Tz>

impl<Tz> Sub<TimeDelta> for DateTime<Tz>

where Tz: TimeZone,

Subtract TimeDelta from DateTime.

This is the same as the addition with a negated TimeDelta.

As a part of Chrono’s [leap second handling] the subtraction assumes that there is no leap second ever, except when the DateTime itself represents a leap second in which case the assumption becomes that there is exactly a single leap second ever.

Panics

Panics if the resulting date would be out of range. Consider using DateTime<Tz>::checked_sub_signed to get an Option instead.
