Enum arrow_schema::IntervalUnit

pub enum IntervalUnit {
    YearMonth,
    DayTime,
    MonthDayNano,
}

YEAR_MONTH, DAY_TIME, MONTH_DAY_NANO interval in SQL style.

Variants

YearMonth

Indicates the number of elapsed whole months, stored as 4-byte integers.

DayTime

Indicates the number of elapsed days and milliseconds, stored as 2 contiguous 32-bit integers (days, milliseconds) (8-bytes in total).

MonthDayNano

A triple of the number of elapsed months, days, and nanoseconds. The values are stored contiguously in 16 byte blocks. Months and days are encoded as 32 bit integers and nanoseconds is encoded as a 64 bit integer. All integers are signed. Each field is independent (e.g. there is no constraint that nanoseconds have the same sign as days or that the quantity of nanoseconds represents less than a day’s worth of time).

Trait Implementations

impl Clone for IntervalUnit

fn clone(&self) -> IntervalUnit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IntervalUnit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for IntervalUnit

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IntervalUnit

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for IntervalUnit

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for IntervalUnit

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

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

fn lt(&self, other: &Rhs) -> bool

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

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

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

fn ge(&self, other: &Rhs) -> bool

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