Enum FieldPlan 

enum FieldPlan {
    Scalar,
    Struct {
        encoders: Vec<FieldBinding>,
    },
    List {
        items_nullability: Option<Nullability>,
        item_plan: Box<FieldPlan>,
    },
    Decimal {
        size: Option<usize>,
    },
    Uuid,
    Map {
        values_nullability: Option<Nullability>,
        value_plan: Box<FieldPlan>,
    },
    Enum {
        symbols: Arc<[String]>,
    },
}

Per‑site encoder plan for a field. This mirrors the Avro structure, so nested optional branch order can be honored exactly as declared by the schema.

Variants

Scalar

Non-nested scalar/logical type

Struct

Record/Struct with Avro‑ordered children

Fields

encoders: Vec<FieldBinding>

List

Array with item‑site nullability and nested plan

Fields

items_nullability: Option<Nullability>

item_plan: Box<FieldPlan>

Decimal

Avro decimal logical type (bytes or fixed). size=None => bytes(decimal), Some(n) => fixed(n)

Fields

size: Option<usize>

Uuid

Avro UUID logical type (fixed)

Map

Avro map with value‑site nullability and nested plan

Fields

values_nullability: Option<Nullability>

value_plan: Box<FieldPlan>

Enum

Avro enum; maps to Arrow Dictionary<Int32, Utf8> with dictionary values exactly equal and ordered as the Avro enum symbols.

Fields

symbols: Arc<[String]>
