Provided Methods

fn year(&self) -> ChunkedArray<Int32Type>

Extract month from underlying NaiveDateTime representation. Returns the year number in the calendar date.

fn is_leap_year(&self) -> ChunkedArray<BooleanType>

Extract year from underlying NaiveDate representation. Returns whether the year is a leap year.

fn iso_year(&self) -> ChunkedArray<Int32Type>

fn quarter(&self) -> ChunkedArray<Int8Type>

Extract quarter from underlying NaiveDateTime representation. Quarters range from 1 to 4.

fn month(&self) -> ChunkedArray<Int8Type>

Extract month from underlying NaiveDateTime representation. Returns the month number starting from 1.

The return value ranges from 1 to 12.

fn weekday(&self) -> ChunkedArray<Int8Type>

Extract ISO weekday from underlying NaiveDateTime representation. Returns the weekday number where monday = 1 and sunday = 7

fn week(&self) -> ChunkedArray<Int8Type>

Returns the ISO week number starting from 1. The return value ranges from 1 to 53. (The last week of year differs by years.)

fn day(&self) -> ChunkedArray<Int8Type>

Extract day from underlying NaiveDateTime representation. Returns the day of month starting from 1.

The return value ranges from 1 to 31. (The last day of month differs by months.)

fn hour(&self) -> ChunkedArray<Int8Type>

Extract hour from underlying NaiveDateTime representation. Returns the hour number from 0 to 23.

fn minute(&self) -> ChunkedArray<Int8Type>

Extract minute from underlying NaiveDateTime representation. Returns the minute number from 0 to 59.

fn second(&self) -> ChunkedArray<Int8Type>

Extract second from underlying NaiveDateTime representation. Returns the second number from 0 to 59.

fn nanosecond(&self) -> ChunkedArray<Int32Type>

Extract second from underlying NaiveDateTime representation. Returns the number of nanoseconds since the whole non-leap second. The range from 1,000,000,000 to 1,999,999,999 represents the leap second.

fn ordinal(&self) -> ChunkedArray<Int16Type>

Returns the day of year starting from 1.

The return value ranges from 1 to 366. (The last day of year differs by years.)

fn parse_from_str_slice( name: &str, v: &[&str], fmt: &str, tu: TimeUnit ) -> Logical<DatetimeType, Int64Type>
