Memory

Copy values between runtimes or share state that more than one runtime needs to access. Start with Sharing memory to choose a memory primitive, or follow Synchronizing data for practical examples.

Choose a memory primitive

• Serializable — Transfer a value as an independent copy. Changes to the copy do not update the original.
• Synchronizable — Keep shared state in native memory so multiple runtimes can read and write it.
• Shareable — Keep a value on a host runtime and access it from guest runtimes.

Create a value

• createSerializable — Create an opaque reference to a serialized value. Scheduling APIs usually handle serialization for you.
• createSynchronizable — Create a shared value in native memory.
• createShareable — Create a value hosted on a specific runtime.

Inspect a value

• isSerializableRef — Check whether a value is a Serializable reference.
• isSynchronizable — Check whether a value is a Synchronizable.

Customize serialization

• registerCustomSerializable — Define how a custom type is transferred between runtimes.
