Required Associated Types

type Id: Copy + Eq + Hash + IntoStorageKey + From<StorageKey>

type Data

Required Methods

fn serialize(&self) -> Result<(Self::Id, Self::Data), ()>

https://html.spec.whatwg.org/multipage/#serialization-steps

fn deserialize( owner: &GlobalScope, serialized: Self::Data, can_gc: CanGc, ) -> Result<DomRoot<Self>, ()>

where Self: Sized,

https://html.spec.whatwg.org/multipage/#deserialization-steps

fn serialized_storage( data: StructuredData<'_>, ) -> &mut Option<HashMap<Self::Id, Self::Data>>

Returns the field of StructuredDataReader/[StructuredDataWriter] that should be used to read/store serialized instances of this type.

fn deserialized_storage( reader: &mut StructuredDataReader, ) -> &mut Option<HashMap<StorageKey, DomRoot<Self>>>

Returns the field of StructuredDataReader that should be used to store deserialized instances of this type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors
