Module polars_arrow::compute::temporal

Available on crate feature compute_temporal only.

Defines temporal kernels for time and date related functions.

Functions

• can_day
  Checks if an array of type datatype can perform day operation
• can_hour
  Checks if an array of type datatype can perform hour operation
• can_iso_week
  Checks if an array of type data_type can perform ISO week operation
• can_minute
  Checks if an array of type datatype can perform minute operation
• can_month
  Checks if an array of type datatype can perform month operation
• can_nanosecond
  Checks if an array of type datatype can perform nanosecond operation
• can_second
  Checks if an array of type datatype can perform second operation
• can_weekday
  Checks if an array of type data_type can perform weekday operation
• can_year
  Checks if an array of type datatype can perform year operation
• day
  Extracts the days of a temporal array as PrimitiveArray<i8>. Value ranges from 1 to 32 (Last day depends on month). Use can_day to check if this operation is supported for the target ArrowDataType.
• hour
  Extracts the hours of a temporal array as PrimitiveArray<i8>. Value ranges from 0 to 23. Use can_hour to check if this operation is supported for the target ArrowDataType.
• iso_week
  Extracts ISO week of a temporal array as PrimitiveArray<i8> Value ranges from 1 to 53 (Last week depends on the year). Use can_iso_week to check if this operation is supported for the target ArrowDataType
• minute
  Extracts the minutes of a temporal array as PrimitiveArray<i8>. Value ranges from 0 to 59. Use can_minute to check if this operation is supported for the target ArrowDataType.
• month
  Extracts the months of a temporal array as PrimitiveArray<i8>. Value ranges from 1 to 12. Use can_month to check if this operation is supported for the target ArrowDataType.
• nanosecond
  Extracts the nanoseconds of a temporal array as PrimitiveArray<i32>. Value ranges from 0 to 1_999_999_999. The range from 1_000_000_000 to 1_999_999_999 represents the leap second. Use can_nanosecond to check if this operation is supported for the target ArrowDataType.
• second
  Extracts the seconds of a temporal array as PrimitiveArray<i8>. Value ranges from 0 to 59. Use can_second to check if this operation is supported for the target ArrowDataType.
• weekday
  Extracts weekday of a temporal array as PrimitiveArray<i8>. Monday is 1, Tuesday is 2, …, Sunday is 7. Use can_weekday to check if this operation is supported for the target ArrowDataType
• year
  Extracts the years of a temporal array as PrimitiveArray<i32>. Use can_year to check if this operation is supported for the target ArrowDataType.
