Provided Methods§

source

fn hour(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

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

source

fn minute(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

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

source

fn second(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

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

source

fn nanosecond(&self) -> Result<ChunkedArray<Int32Type>, PolarsError>

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.

source

fn day(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

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.)

source

fn weekday(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

Returns the ISO weekday number where monday = 1 and sunday = 7

source

fn week(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

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

source

fn ordinal_day(&self) -> Result<ChunkedArray<Int16Type>, PolarsError>

Returns the day of year starting from 1.

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

source

fn millennium(&self) -> Result<ChunkedArray<Int32Type>, PolarsError>

Calculate the millennium from the underlying NaiveDateTime representation.

source

fn century(&self) -> Result<ChunkedArray<Int32Type>, PolarsError>

Calculate the millennium from the underlying NaiveDateTime representation.

source

fn year(&self) -> Result<ChunkedArray<Int32Type>, PolarsError>

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

source

fn iso_year(&self) -> Result<ChunkedArray<Int32Type>, PolarsError>

source

fn ordinal_year(&self) -> Result<ChunkedArray<Int32Type>, PolarsError>

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

source

fn is_leap_year(&self) -> Result<ChunkedArray<BooleanType>, PolarsError>

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

source

fn quarter(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

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

source

fn month(&self) -> Result<ChunkedArray<Int8Type>, PolarsError>

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

The return value ranges from 1 to 12.

source

fn to_string(&self, format: &str) -> Result<Series, PolarsError>

Convert Time into String with the given format. See chrono strftime/strptime.

source

fn strftime(&self, format: &str) -> Result<Series, PolarsError>

Convert from Time into String with the given format. See chrono strftime/strptime.

Alias for to_string.

source

fn timestamp( &self, tu: TimeUnit ) -> Result<ChunkedArray<Int64Type>, PolarsError>

Convert date(time) object to timestamp in TimeUnit.
