Struct arrow::datatypes::IntervalDayTimeType

source ·
pub struct IntervalDayTimeType {}
Expand description

A “calendar” interval type in days and milliseconds.

§Representation

This type is stored as a single 64 bit integer, interpreted as two i32 fields:

  1. the number of elapsed days
  2. The number of milliseconds (no leap seconds),
 ┌──────────────┬──────────────┐
 │     Days     │ Milliseconds │
 │  (32 bits)   │  (32 bits)   │
 └──────────────┴──────────────┘
 0              31            63 bit offset

Please see the Arrow Spec for more details

§Note on Comparing and Ordering for Calendar Types

Values of IntervalDayTimeType are compared using their binary representation, which can lead to surprising results. Please see the description of ordering on IntervalMonthDayNanoType for more details

Implementations§

source§

impl IntervalDayTimeType

source

pub fn make_value( days: i32, millis: i32, ) -> <IntervalDayTimeType as ArrowPrimitiveType>::Native

Creates a IntervalDayTimeType::Native

§Arguments
  • days - The number of days (+/-) represented in this interval
  • millis - The number of milliseconds (+/-) represented in this interval
source

pub fn to_parts( i: <IntervalDayTimeType as ArrowPrimitiveType>::Native, ) -> (i32, i32)

Turns a IntervalDayTimeType into a tuple of (days, milliseconds)

§Arguments
  • i - The IntervalDayTimeType to convert
