Variants
Null
Boolean(bool)
A binary true or false.
Utf8(&'a str)
A UTF8 encoded string type.

An unsigned 16-bit integer number.
UInt32(u32)
An unsigned 32-bit integer number.
UInt64(u64)
An unsigned 64-bit integer number.
Int8(i8)
An 8-bit integer number.
Int16(i16)
A 16-bit integer number.
Int32(i32)
A 32-bit integer number.
Int64(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.
Struct(Vec<AnyValue<'a>, Global>, &'a [Field])
StructOwned(Box<(Vec<AnyValue<'a>, Global>, Vec<Field, Global>), Global>)
Utf8Owned(SmartString<LazyCompact>)
A UTF8 encoded string type.
Binary(&'a [u8])
BinaryOwned(Vec<u8, Global>)
