Module variant_to_arrow 

Macros

define_variant_to_primitive_builder 🔒

Structs

EncodedVariantToArrowRowBuilder 🔒

FakeNullBuilder 🔒

MapVariantToArrowRowBuilder 🔒

Builder for converting variant objects into Arrow MapArrays.

StructVariantToArrowRowBuilder 🔒

UnionChildBuilder 🔒

UnionVariantToArrowRowBuilder 🔒

Builder for converting variant values into a [UnionArray].

VariantPathRowBuilder 🔒

A thin wrapper whose only job is to extract a specific path from a variant value and pass the result to a nested builder.

VariantToBinaryArrowRowBuilder 🔒

VariantToBinaryVariantArrowRowBuilder 🔒

Builder for creating VariantArray output (for path extraction without type conversion)

VariantToBooleanArrowRowBuilder 🔒

VariantToDecimalArrowRowBuilder 🔒

Builder for converting variant values to arrow Decimal values

VariantToFixedSizeListArrowRowBuilder 🔒

VariantToListArrowRowBuilder 🔒

VariantToNullArrowRowBuilder 🔒

VariantToPrimitiveArrowRowBuilder 🔒

VariantToStringArrowBuilder 🔒

VariantToTimestampArrowRowBuilder 🔒

VariantToTimestampNtzArrowRowBuilder 🔒

VariantToUuidArrowRowBuilder 🔒

Builder for converting variant values to FixedSizeBinary(16) for UUIDs

Enums

ArrayVariantToArrowRowBuilder 🔒

ListElementBuilder 🔒

Element builder for list variants, supporting both typed (for crate::variant_get()) and shredded (for crate::shred_variant()) output modes.

PrimitiveVariantToArrowRowBuilder 🔒

Builder for converting primitive variant values to Arrow arrays. It is used by both VariantToArrowRowBuilder (below) and VariantToShreddedPrimitiveVariantRowBuilder (in shred_variant.rs).

VariantToArrowRowBuilder 🔒

Builder for converting variant values into strongly typed Arrow arrays.

Functions

make_primitive_variant_to_arrow_row_builder 🔒

Creates a row builder that converts primitive Variant values into the requested Arrow data type.

make_typed_variant_to_arrow_row_builder 🔒

make_variant_to_arrow_row_builder 🔒

union_child_rank 🔒

Ranks how exactly a union child of type data_type can represent a variant value’s runtime type: 0 is the value’s natural Arrow type, higher ranks are lossless widenings, and None means the child cannot represent the value losslessly. Every pair admitted here must be convertible by the corresponding row builder.
