Trait DecodeDataFromRecordBatch

pub trait DecodeDataFromRecordBatch
where
    Self: Sized + Into<Data> + ArrowSchemaProvider,
{
    // Required method
    fn decode_data_batch(
        metadata: &HashMap<String, String>,
        record_batch: RecordBatch,
    ) -> Result<Vec<Data>, EncodingError>;
}

Decodes raw Data objects from Apache Arrow RecordBatch format.

Required Methods

fn decode_data_batch( metadata: &HashMap<String, String>, record_batch: RecordBatch, ) -> Result<Vec<Data>, EncodingError>

Decodes a RecordBatch into raw Data values, using the provided metadata.

Errors

Returns an EncodingError if the decoding fails.

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.
