Datetime(i64, TimeUnit, &'a Option<String>)

A 64-bit date representing the elapsed time since UNIX epoch (1970-01-01) in nanoseconds (64 bits).

Duration(i64, TimeUnit)

Time(i64)

Categorical(u32, &'a RevMapping)

List(Series)

Nested type, contains arrays that are filled with one of the datetypes.

Object(&'a (dyn PolarsObjectSafe + 'static))

Can be used to fmt and implements Any, so can be downcasted to the proper value type.

Implementations

impl<'a> AnyValue<'a>

pub fn add(&self, rhs: &AnyValue<'b>) -> AnyValue<'a>

pub fn to_static(&self) -> Result<AnyValue<'static>, PolarsError>

Try to coerce to an AnyValue with static lifetime. This can be done if it does not borrow any values.

Trait Implementations

impl<'a> Clone for AnyValue<'a>

pub fn clone(&self) -> AnyValue<'a>

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for AnyValue<'a>

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'_> Display for AnyValue<'_>

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
