Struct HashConsDedupSerializer 

pub struct HashConsDedupSerializer {
    ser: RefCell<TypeMap<SerializeTableMapper>>,
    de: RefCell<TypeMap<DeserializeTableMapper>>,
}

HashCons supports serializing each value to a unique id in order to serialize highly-shared values without explosion.

Note that the deduplication scheme is highly order-dependent: we serialize the real value the first time it comes up, and use ids only subsequent times. This relies on the fact that derive(Serialize, Deserialize) traverse the value in the same order.

Fields

ser: RefCell<TypeMap<SerializeTableMapper>>

de: RefCell<TypeMap<DeserializeTableMapper>>

Trait Implementations

impl Default for HashConsDedupSerializer

fn default() -> HashConsDedupSerializer

Returns the “default value” for a type.

impl HashConsSerializerState for HashConsDedupSerializer

fn record_serialized<T: Mappable>(&self, id: HashConsId) -> Option<bool>

Record that this type is being serialized. Return None if we’re not deduplicating values, otherwise return whether this item was newly recorded.

fn record_deserialized<T: Mappable>(&self, id: HashConsId, val: HashConsed<T>)

Record that we deserialized this type.

fn get_deserialized_val<T: Mappable>( &self, id: HashConsId, ) -> Option<HashConsed<T>>

Find the previously-deserialized type with that id.
