Provided Methods

fn as_time(&self, fmt: Option<&str>, cache: bool) -> PolarsResult<TimeChunked>

Available on crate feature dtype-time only.

Parsing string values and return a TimeChunked

fn as_date_not_exact(&self, fmt: Option<&str>) -> PolarsResult<DateChunked>

Available on crate feature dtype-date only.

Parsing string values and return a DateChunked Different from as_date this function allows matches that not contain the whole string e.g. “foo-2021-01-01-bar” could match “2021-01-01”

fn as_datetime_not_exact(
    &self,
    fmt: Option<&str>,
    tu: TimeUnit
) -> PolarsResult<DatetimeChunked>

Available on crate feature dtype-datetime only.

Parsing string values and return a DatetimeChunked Different from as_datetime this function allows matches that not contain the whole string e.g. “foo-2021-01-01-bar” could match “2021-01-01”

fn as_date(&self, fmt: Option<&str>, cache: bool) -> PolarsResult<DateChunked>

Available on crate feature dtype-date only.

Parsing string values and return a DateChunked

fn as_datetime(
    &self,
    fmt: Option<&str>,
    tu: TimeUnit,
    cache: bool,
    tz_aware: bool
) -> PolarsResult<DatetimeChunked>

Available on crate feature dtype-datetime only.

Parsing string values and return a DatetimeChunked
