Trait DedupSerializerState 

pub trait DedupSerializerState: Sized {
    // Required methods
    fn record_serialized<T: Dedup>(
        &self,
        value: &T,
    ) -> Option<Result<DedupId, DedupId>>;
    fn record_deserialized<T: Dedup>(&self, id: DedupId, value: T);
    fn get_deserialized<T: Dedup>(&self, id: DedupId) -> Option<T>;
}

The state threaded through (de)serialization to deduplicate values. Use () to serialize values normally and DedupSerializer to deduplicate them.

Required Methods

fn record_serialized<T: Dedup>( &self, value: &T, ) -> Option<Result<DedupId, DedupId>>

Record that we’re serializing this value. Returns None if we’re not deduplicating values, Some(Ok(id)) the first time we meet a given value (it must then be serialized in full), and Some(Err(id)) afterwards (only the id must be serialized).

fn record_deserialized<T: Dedup>(&self, id: DedupId, value: T)

Record that we deserialized the value with this id.

fn get_deserialized<T: Dedup>(&self, id: DedupId) -> Option<T>

Find the previously-deserialized value with that id.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl DedupSerializerState for ()

Don’t deduplicate anything.

fn record_serialized<T: Dedup>( &self, _value: &T, ) -> Option<Result<DedupId, DedupId>>

fn record_deserialized<T: Dedup>(&self, _id: DedupId, _value: T)

fn get_deserialized<T: Dedup>(&self, _id: DedupId) -> Option<T>
