Required Associated Types

type ValueT<'a>: Clone where Self: 'a

type ZeroableValueT<'a>: Zeroable + From<Self::ValueT<'a>> where Self: 'a

type ValueIterT<'a>: DoubleEndedIterator<Item = Self::ValueT<'a>> + TrustedLen + Send + Sync where Self: 'a

Required Methods

fn with_validity_typed(self, validity: Option<Bitmap>) -> Self

fn full_null(length: usize, dtype: ArrowDataType) -> Self

Provided Methods

fn get(&self, idx: usize) -> Option<Self::ValueT<'_>>

unsafe fn get_unchecked(&self, idx: usize) -> Option<Self::ValueT<'_>>

Safety

It is the callers responsibility that the idx < self.len().

fn last(&self) -> Option<Self::ValueT<'_>>

fn value(&self, idx: usize) -> Self::ValueT<'_>

unsafe fn value_unchecked(&self, idx: usize) -> Self::ValueT<'_>

Safety

It is the callers responsibility that the idx < self.len().

fn as_slice(&self) -> Option<&[Self::ValueT<'_>]>

fn iter( &self, ) -> ZipValidity<Self::ValueT<'_>, Self::ValueIterT<'_>, BitmapIter<'_>>

fn values_iter(&self) -> Self::ValueIterT<'_>

fn from_vec(v: Vec<Self::ValueT<'_>>, dtype: ArrowDataType) -> Self

fn from_zeroable_vec( v: Vec<Self::ZeroableValueT<'_>>, dtype: ArrowDataType, ) -> Self

fn full(length: usize, value: Self::ValueT<'_>, dtype: ArrowDataType) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
