Variants

Null

Boolean

UInt64

Int64

Float64

Utf8

Json

JSON-serialized fallback for attributes whose values are heterogeneous across rows or within a list. The wire type is LargeUtf8; values are round-tripped through JSON.

Implementations

impl ProjectedValueSpec

pub fn to_arrow_type(&self) -> DataType

Trait Implementations

impl Clone for ProjectedValueSpec

fn clone(&self) -> ProjectedValueSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectedValueSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProjectedValueSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProjectedValueSpec

fn eq(&self, other: &ProjectedValueSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ProjectedValueSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
