Enum sqlx_exasol::etl::ExaExport
source · pub enum ExaExport {
Setup(BoxFuture<'static, Result<ExaSocket>>, bool),
Reading(ExaExportReader),
}Expand description
An ETL EXPORT worker.
The type implements AsyncRead and is Send and Sync so it can be freely used
in any data pipeline.
§IMPORTANT
Dropping a reader before it returned EOF will result in the EXPORT query returning an error.
While not necessarily a problem if you’re not interested in the whole export, there’s no way to
circumvent that other than handling the error in code.
