Expand description

Represents the LargeList Arrow type.

Trait Implementations§

Source§

impl<T> ArrowDeserialize for LargeVec<T>
where T: ArrowDeserialize + ArrowEnableVecForType + 'static, <T as ArrowDeserialize>::ArrayType: 'static, for<'b> &'b <T as ArrowDeserialize>::ArrayType: IntoIterator,

Source§

type ArrayType = ListArray<i64>

The arrow2::Array type corresponding to this field
Source§

fn arrow_deserialize( v: Option<Box<dyn Array>>, ) -> Option<<Self as ArrowField>::Type>

Deserialize this field from arrow
Source§

impl<T> ArrowField for LargeVec<T>
where T: ArrowField + ArrowEnableVecForType,

Source§

type Type = Vec<<T as ArrowField>::Type>

This should be Self except when implementing large offset and fixed placeholder types. For the later, it should refer to the actual type. For example when the placeholder type is LargeString, this should be String.
Source§

fn data_type() -> DataType

The DataType
Source§

impl<T> ArrowSerialize for LargeVec<T>
where T: ArrowSerialize + ArrowEnableVecForType + 'static, <T as ArrowSerialize>::MutableArrayType: Default,

Source§

type MutableArrayType = MutableListArray<i64, <T as ArrowSerialize>::MutableArrayType>

The arrow2::array::MutableArray that holds this value
Source§

fn new_array() -> Self::MutableArrayType

Create a new mutable array
Source§

fn arrow_serialize( v: &<Self as ArrowField>::Type, array: &mut Self::MutableArrayType, ) -> Result<()>

Serialize this field to arrow
