pub struct SchemaField {
pub id: i32,
pub name: String,
pub required: bool,
pub iceberg_type: String,
pub initial_default: Option<Value>,
pub write_default: Option<Value>,
}Expand description
One field from the current Iceberg table schema (Phase G).
Parsed from schemas[current-schema-id].fields in metadata.json.
Used by SchemaFiller to inject missing columns when reading old files.
Fields§
§id: i32§name: String§required: bool§iceberg_type: StringIceberg type string, e.g. "int", "string", "timestamptz".
initial_default: Option<Value>Value injected when reading old files that predate this field.
None → null is used.
write_default: Option<Value>Default value written to new files. Same as initial_default in most cases.
