Trait for any content that can be served via WASM

This trait provides the abstraction layer between content types (datasets, courses, models, raw data) and the serving infrastructure.

Required Methods

fn schema(&self) -> ContentSchema

Returns the content schema for validation and UI generation

fn validate(&self) -> Result<ValidationReport>

Validates content integrity

Errors

Returns an error if validation cannot be performed.

fn to_arrow(&self) -> Result<RecordBatch>

Converts content to Arrow RecordBatch for efficient transfer

Errors

Returns an error if the content cannot be converted to Arrow format.

fn metadata(&self) -> ContentMetadata

Returns content metadata for indexing and discovery

fn content_type(&self) -> ContentTypeId

Returns content type identifier

fn chunks( &self, chunk_size: usize, ) -> Box<dyn Iterator<Item = Result<RecordBatch>> + Send>

Chunk iterator for streaming large content

fn to_bytes(&self) -> Result<Vec<u8>>

Get the raw bytes representation (for serialization)

Errors

Returns an error if the content cannot be serialized to bytes.

Dyn Compatibility

This trait is dyn compatible.

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