Module arrow::compute::kernels::cast_utils

Parser implementations for converting strings to Arrow types

Used by the CSV and JSON readers to convert strings to Arrow types

Structs

• IntervalParseConfig
  Config to parse interval strings

Enums

• IntervalUnit
  Represents the units of an interval, with each variant corresponding to a bit in the interval’s bitfield representation

Traits

• Parser
  Specialized parsing implementations to convert strings to Arrow types.

Functions

• parse_decimal
  Parse the string format decimal value to i128/i256 format and checking the precision and scale. The result value can’t be out of bounds.
• parse_interval_day_time
  Parse human-readable interval string to Arrow IntervalDayTimeType
• parse_interval_month_day_nano
  Parse human-readable interval string to Arrow IntervalMonthDayNanoType
• parse_interval_month_day_nano_config
  Parse human-readable interval string to Arrow IntervalMonthDayNanoType
• parse_interval_year_month
  Parse human-readable interval string to Arrow IntervalYearMonthType
• string_to_datetime
  Accepts a string and parses it relative to the provided timezone
• string_to_time_nanoseconds
  Accepts a string in ISO8601 standard format and some variants and converts it to nanoseconds since midnight.
• string_to_timestamp_nanos
  Accepts a string in RFC3339 / ISO8601 standard format and some variants and converts it to a nanosecond precision timestamp.

Type Aliases

• MonthDayNano
  A tuple representing (months, days, nanoseconds) in an interval
