Required Methods

fn parse_from_str_slice(name: &str, v: &[&str], fmt: &str) -> DateChunked

Provided Methods

fn year(&self) -> Int32Chunked

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

fn iso_year(&self) -> Int32Chunked

This year number might not match the calendar year number.

fn quarter(&self) -> UInt32Chunked

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

fn month(&self) -> UInt32Chunked

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

The return value ranges from 1 to 12.

fn weekday(&self) -> UInt32Chunked

Extract weekday from underlying NaiveDate representation. Returns the weekday number where monday = 0 and sunday = 6

fn week(&self) -> UInt32Chunked

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) -> UInt32Chunked

Extract day from underlying NaiveDate 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 ordinal(&self) -> UInt32Chunked

Returns the day of year starting from 1.

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