Trait IntoRecordBatchReader 

pub trait IntoRecordBatchReader<SourceKind = RecordBatchReaderSourceKind> {
    type Reader: RecordBatchReader;

    // Required method
    fn into_record_batch_reader(self) -> Result<Self::Reader, AppendError>;
}

Convert an Arrow batch source into a schema-bearing RecordBatchReader.

Implementations preserve non-Send readers. The SourceKind parameter is an inference-only coherence marker and should not normally be specified by callers.

Required Associated Types

type Reader: RecordBatchReader

Reader produced from this source.

Required Methods

fn into_record_batch_reader(self) -> Result<Self::Reader, AppendError>

Convert this source without collecting its batches.

Dyn Compatibility

This trait is dyn compatible.

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