Enums

DatePart

Valid parts to extract from date/time/timestamp arrays.

Traits

ChronoDateExt 🔒

ExtractDatePartExt 🔒

Implement the specialized functions for extracting date part from temporal arrays.

Functions

date_part

Given an array, return a new array with the extracted DatePart as signed 32-bit integer values.

get_date_time_part_extract_fn 🔒

Returns function to extract relevant DatePart from types like a NaiveDateTime or DateTime.

get_tz 🔒

Extract optional [Tz] from timestamp data types, returning error if called with a non-timestamp type.

subsecond 🔒

Fractional second of v, counted in units per second, rescaled to target per second. Both scales divide one second evenly, so the conversion is exact when scaling up and truncating when scaling down.

timestamp_time_part 🔒

Extracts a time-of-day part from a timestamp array without a timezone using integer arithmetic. Returns None for parts that require a calendar conversion.

units_per_second 🔒

Number of ticks in one second for timestamps of type T.
