Struct arrow2_convert::field::FixedSizeVec

pub struct FixedSizeVec<T, const SIZE: usize> { /* private fields */ }

Represents the FixedSizeList Arrow type.

Trait Implementations

impl<T, const SIZE: usize> ArrowDeserialize for FixedSizeVec<T, SIZE>where T: ArrowDeserialize + ArrowEnableVecForType + 'static, <T as ArrowDeserialize>::ArrayType: 'static, for<'b> &'b <T as ArrowDeserialize>::ArrayType: IntoIterator,

type ArrayType = FixedSizeListArray

The arrow2::Array type corresponding to this field

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

Deserialize this field from arrow

impl<T, const SIZE: usize> ArrowField for FixedSizeVec<T, SIZE>where T: ArrowField + ArrowEnableVecForType,

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

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.

fn data_type() -> DataType

The DataType

impl<T, const SIZE: usize> ArrowSerialize for FixedSizeVec<T, SIZE>where T: ArrowSerialize + ArrowEnableVecForType + 'static, <T as ArrowSerialize>::MutableArrayType: Default,

type MutableArrayType = MutableFixedSizeListArray<<T as ArrowSerialize>::MutableArrayType>

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

fn new_array() -> Self::MutableArrayType

Create a new mutable array

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

Serialize this field to arrow
