Trait EncodeToRecordBatch

pub trait EncodeToRecordBatch
where
    Self: Sized + ArrowSchemaProvider,
{
    // Required methods
    fn encode_batch(
        metadata: &HashMap<String, String>,
        data: &[Self],
    ) -> Result<RecordBatch, ArrowError>;
    fn metadata(&self) -> HashMap<String, String>;

    // Provided method
    fn chunk_metadata(chunk: &[Self]) -> HashMap<String, String> { ... }
}

Required Methods

fn encode_batch( metadata: &HashMap<String, String>, data: &[Self], ) -> Result<RecordBatch, ArrowError>

fn metadata(&self) -> HashMap<String, String>

Provided Methods

fn chunk_metadata(chunk: &[Self]) -> HashMap<String, String>

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.
