pub trait FormatRead: Send + Sync {
    // Required method
    fn read<'life0, 'async_trait>(
        &'life0 self,
        reader: Box<dyn FileReader>,
    ) -> Pin<Box<dyn Future<Output = Result<BatchStream, TransferredError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Decodes a file’s bytes into Arrow batches.

Required Methods

fn read<'life0, 'async_trait>( &'life0 self, reader: Box<dyn FileReader>, ) -> Pin<Box<dyn Future<Output = Result<BatchStream, TransferredError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Read one open file handle into a stream of Arrow batches.
