Supported types for OwnedColumn

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Boolean(Vec<bool>)

Boolean columns

SmallInt(Vec<i16>)

i16 columns

Int(Vec<i32>)

i32 columns

BigInt(Vec<i64>)

i64 columns

VarChar(Vec<String>)

String columns

Int128(Vec<i128>)

i128 columns

Decimal75(Precision, i8, Vec<S>)

Decimal columns

Scalar(Vec<S>)

Scalar columns

TimestampTZ(PoSQLTimeUnit, PoSQLTimeZone, Vec<i64>)

Timestamp columns

Implementations

impl<S: Scalar> OwnedColumn<S>

pub fn len(&self) -> usize

Returns the length of the column.

pub fn is_empty(&self) -> bool

Returns true if the column is empty.

pub fn column_type(&self) -> ColumnType

Returns the type of the column.

Trait Implementations

impl<S: Clone + Scalar> Clone for OwnedColumn<S>

fn clone(&self) -> OwnedColumn<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug + Scalar> Debug for OwnedColumn<S>

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

Formats the value using the given formatter.

impl<S: Scalar> From<OwnedColumn<S>> for ArrayRef

fn from(value: OwnedColumn<S>) -> Self

Converts to this type from the input type.

impl<S: PartialEq + Scalar> PartialEq for OwnedColumn<S>

fn eq(&self, other: &OwnedColumn<S>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<S: Scalar> TryFrom<&Arc<dyn Array>> for OwnedColumn<S>

type Error = OwnedArrowConversionError

The type returned in the event of a conversion error.

fn try_from(value: &ArrayRef) -> Result<Self, Self::Error>

Performs the conversion.

impl<S: Scalar> TryFrom<Arc<dyn Array>> for OwnedColumn<S>

type Error = OwnedArrowConversionError

The type returned in the event of a conversion error.

fn try_from(value: ArrayRef) -> Result<Self, Self::Error>

Performs the conversion.

impl<S: Eq + Scalar> Eq for OwnedColumn<S>

impl<S: Scalar> StructuralPartialEq for OwnedColumn<S>
