Enum ObjectAdditionalProperties 

pub enum ObjectAdditionalProperties {
    Denied,
    Closed,
    Untyped,
    Typed {
        value_type: Box<SchemaType>,
    },
}

How an Object handles additionalProperties. Q2.3 split the pre-existing bool into a three-way enum so the generator can emit a typed BTreeMap<String, T> when the spec provides a value-type schema instead of degrading to serde_json::Value.

Variants

Denied

additionalProperties: false: the document itself forbids extra keys. No catch-all field is emitted, and because the rule is stated rather than assumed the generated struct may also reject extra keys — which it must, to stay distinguishable as an untagged union branch.

Closed

The keyword is omitted. JSON Schema leaves such an object open; the generator projects it closed (no catch-all field) while no required unknown member forces an open carrier. Unlike Self::Denied this is the generator’s projection, not a rule the document stated, so the struct stays tolerant of keys it does not declare.

Untyped

additionalProperties: true — extra keys captured as BTreeMap<String, serde_json::Value>.

Typed

additionalProperties: <schema> — extra keys captured as BTreeMap<String, T> where T comes from the schema.

Fields

value_type: Box<SchemaType>

Implementations

impl ObjectAdditionalProperties

pub fn is_open(&self) -> bool

True when extra keys are accepted (regardless of typing). Used by callers that only care whether the field exists.

pub fn denies_unknown_keys(&self) -> bool

True when the document forbids extra keys, as opposed to the generator merely projecting a closed struct. Only this case may tighten the generated struct’s own deserialization.

Trait Implementations

impl Clone for ObjectAdditionalProperties

fn clone(&self) -> ObjectAdditionalProperties

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObjectAdditionalProperties

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
