Struct ResolvedField 

pub struct ResolvedField {
    pub name: FieldName,
    pub mapping: Mapping,
    pub nullable: bool,
    pub array: bool,
    pub children: Vec<ResolvedField>,
}

One field within an IndexMapping: the document key it lands under, its resolved Mapping (the mapping_type is always present), whether the value can be null, and the fields nested under it for object / nested types.

Fields

name: FieldName

mapping: Mapping

nullable: bool

Whether this field’s value can be null in the document. Derived by the source while resolving the mapping — the config does not state it, but the source knows (a column’s NOT NULL, a primary key, a default, the arity of a relation, an aggregate’s zero-row behavior). A sink ignores it; it exists for consumers that turn the mapping into typed bindings, where nullable is the difference between T and Option<T>.

array: bool

Whether this field’s value is a flat scalar array (the mapping_type is then the element type — OpenSearch has no array type). True only for ids; a consumer turning the mapping into typed bindings reads it as the difference between T and Vec<T>.

children: Vec<ResolvedField>
