Required Methods

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 parse_from_str_slice( name: &str, v: &[&str], fmt: &str ) -> Logical<TimeType, Int64Type>
