Configuration for protobuf to Arrow conversions.

This struct allows customizing how protobuf types are mapped to Arrow types, similar to Python’s ProtarrowConfig.

Fields

timestamp_tz: Option<Arc<str>>

Timezone for timestamp values. Default: Some(“UTC”) Set to None for timezone-naive timestamps.

timestamp_unit: TimeUnit

Time unit for timestamp values. Default: Nanosecond

time_unit: TimeUnit

Time unit for time of day values. Default: Nanosecond

duration_unit: TimeUnit

Time unit for duration values. Default: Nanosecond

list_value_name: Arc<str>

Name for list item field. Default: “item”

map_value_name: Arc<str>

Name for map value field. Default: “value”

list_nullable: bool

Whether list fields can be null. Default: false

map_nullable: bool

Whether map fields can be null. Default: false

list_value_nullable: bool

Whether list element values can be null. Default: false

map_value_nullable: bool

Whether map values can be null. Default: false

use_large_string: bool

Whether to use LargeUtf8 instead of Utf8 for string fields. Default: false

use_large_binary: bool

Whether to use LargeBinary instead of Binary for bytes fields. Default: false

use_large_list: bool

Whether to use LargeList instead of List for repeated fields. Default: false

enum_repr: EnumRepr

How to represent enum fields in Arrow. Default: Int32 When String, use_large_string controls Utf8 vs LargeUtf8. When Binary, use_large_binary controls Binary vs LargeBinary.

confluent_wire_policy: ConfluentWirePolicy

Policy for stripping Confluent Schema Registry wire format prefix. Default: Raw
