}

Defines the minimal set of operations that must be supported by all data types stored in DBSP batches.

This trait is object safe and can be invoked via dynamic dispatch.

Required Methods

fn default_hash(&self) -> u64

Compute a hash of the object using default hasher and seed.

fn dyn_hash(&self, hasher: &mut dyn Hasher)

fn as_data(&self) -> &dyn Data

Cast any type that implements this trait to &dyn Data.

This method will not be needed once trait downcasting has been stabilized.

fn as_data_mut(&mut self) -> &mut dyn Data

Cast any type that implements this trait to &mut dyn Data.

This method will not be needed once trait downcasting has been stabilized.

Trait Implementations

impl Checkpoint for dyn Data + 'static

fn checkpoint(&self) -> Result<Vec<u8>, Error>

fn restore(&mut self, data: &[u8]) -> Result<(), Error>

impl Deserialize<Box<dyn Data>, Deserializer> for ()

fn deserialize( &self, _deserializer: &mut Deserializer, ) -> Result<Box<DynData>, <Deserializer as Fallible>::Error>

Deserializes using the given deserializer

Dyn Compatibility

This trait is dyn compatible.

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