Expand description

The public API for defining new extension DTypes.

Required Associated Types§

Source

type Metadata: 'static + Send + Sync + Clone + Debug + Display + Eq + Hash

Associated type containing the deserialized metadata for this extension type

Required Methods§

Source

fn id(&self) -> ExtID

Returns the ID for this extension type.

Source

fn validate_dtype( &self, metadata: &Self::Metadata, storage_dtype: &DType, ) -> VortexResult<()>

Validate that the given storage type is compatible with this extension type.

Provided Methods§

Source

fn serialize(&self, metadata: &Self::Metadata) -> VortexResult<Vec<u8>>

Serialize the metadata into a byte vector.

Source

fn deserialize(&self, metadata: &[u8]) -> VortexResult<Self::Metadata>

Deserialize the metadata from a byte slice.

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.
