• date32_to_date
  converts a i32 representing a date32 to NaiveDate
• date32_to_date_opt
  converts a i32 representing a date32 to NaiveDate
• date32_to_datetime
  converts a i32 representing a date32 to NaiveDateTime
• date32_to_datetime_opt
  converts a i32 representing a date32 to NaiveDateTime
• date64_to_date
  converts a i64 representing a date64 to NaiveDate
• date64_to_datetime
  converts a i64 representing a date64 to NaiveDateTime
• duration_ms_to_duration
  converts a i64 representing a duration(ms) to Duration
• duration_ns_to_duration
  converts a i64 representing a duration(ns) to Duration
• duration_s_to_duration
  converts a i64 representing a duration(s) to Duration
• duration_us_to_duration
  converts a i64 representing a duration(us) to Duration
• parse_offset
  Parses an offset of the form "+WX:YZ" or "UTC" into FixedOffset.
• time32ms_to_time
  converts a i32 representing a time32(ms) to NaiveTime
• time32s_to_time
  converts a i32 representing a time32(s) to NaiveTime
• time64ns_to_time
  converts a i64 representing a time64(ns) to NaiveTime
• time64ns_to_time_opt
  converts a i64 representing a time64(ns) to NaiveTime
• time64us_to_time
  converts a i64 representing a time64(us) to NaiveTime
• time64us_to_time_opt
  converts a i64 representing a time64(us) to NaiveTime
• timestamp_ms_to_datetime
  converts a i64 representing a timestamp(ms) to NaiveDateTime
• timestamp_ms_to_datetime_opt
  converts a i64 representing a timestamp(ms) to NaiveDateTime
• timestamp_ns_to_datetime
  converts a i64 representing a timestamp(ns) to NaiveDateTime
• timestamp_ns_to_datetime_opt
  converts a i64 representing a timestamp(ns) to NaiveDateTime
• timestamp_s_to_datetime
  converts a i64 representing a timestamp(s) to NaiveDateTime
• timestamp_s_to_datetime_opt
  converts a i64 representing a timestamp(s) to NaiveDateTime
• timestamp_to_datetime
  Converts a timestamp in time_unit and timezone into chrono::DateTime.
• timestamp_to_naive_datetime
  Converts a timestamp in time_unit and timezone into chrono::DateTime.
• timestamp_us_to_datetime
  converts a i64 representing a timestamp(us) to NaiveDateTime
• timestamp_us_to_datetime_opt
  converts a i64 representing a timestamp(us) to NaiveDateTime
• timeunit_scale
  Calculates the scale factor between two TimeUnits. The function returns the scale that should multiply the TimeUnit “b” to have the same time scale as the TimeUnit “a”.
• utf8_to_naive_timestamp_ns
  Parses a Utf8Array to naive timestamp, i.e. PrimitiveArray<i64> with type Timestamp(Nanosecond, None). Timezones are ignored. Null elements remain null; non-parsable elements are set to null.
• utf8_to_naive_timestamp_ns_scalar
  Parses value to Option<i64> consistent with the Arrow’s definition of timestamp without timezone.
• utf8_to_naive_timestamp_scalar
  Parses value to Option<i64> consistent with the Arrow’s definition of timestamp without timezone. Returns in scale tz of TimeUnit.
• utf8_to_timestamp_ns
  Parses a Utf8Array to a timeozone-aware timestamp, i.e. PrimitiveArray<i64> with type Timestamp(Nanosecond, Some(timezone)).
• utf8_to_timestamp_ns_scalar
  Parses value to Option<i64> consistent with the Arrow’s definition of timestamp with timezone. tz must be built from timezone (either via parse_offset or chrono-tz).
• utf8_to_timestamp_scalar
  Parses value to Option<i64> consistent with the Arrow’s definition of timestamp with timezone. tz must be built from timezone (either via parse_offset or chrono-tz). Returns in scale tz of TimeUnit.
