Enum DType

pub enum DType {
    Null,
    Bool(Nullability),
    Primitive(PType, Nullability),
    Utf8(Nullability),
    Binary(Nullability),
    Struct(StructDType, Nullability),
    List(Arc<DType>, Nullability),
    Extension(ExtDType, Nullability),
}

Array logical types.

Vortex arrays preserve a single logical type, while the encodings allow for multiple physical types to encode that type.

Trait Implementations

impl Clone for DType

fn clone(&self) -> DType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DType

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

Formats the value using the given formatter.

impl Display for DType

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

Formats the value using the given formatter.

impl From<PType> for &DType

fn from(item: PType) -> Self

Converts to this type from the input type.

impl From<PType> for DType

fn from(item: PType) -> Self

Converts to this type from the input type.

impl Hash for DType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DType

fn eq(&self, other: &DType) -> 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 PartialOrd for DType

fn partial_cmp(&self, other: &DType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<&DType> for PType

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(value: &DType) -> VortexResult<Self>

Performs the conversion.

impl Eq for DType

impl StructuralPartialEq for DType
