Enum arrow::datatypes::DateUnit

pub enum DateUnit {
    Day,
    Millisecond,
}

Date is either a 32-bit or 64-bit type representing elapsed time since UNIX epoch (1970-01-01) in days or milliseconds.

Variants

Day

Days since the UNIX epoch.

Millisecond

Milliseconds indicating UNIX time elapsed since the epoch (no leap seconds), where the values are evenly divisible by 86400000.

impl Ord for DateUnit

fn cmp(&self, other: &DateUnit) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<DateUnit> for DateUnit

fn eq(&self, other: &DateUnit) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<DateUnit> for DateUnit

fn partial_cmp(&self, other: &DateUnit) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DateUnit

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer,
