Struct tokio_postgres::CopyInSink [−][src]
pub struct CopyInSink<T> { /* fields omitted */ }
A sink for COPY ... FROM STDIN
query data.
The copy must be explicitly completed via the Sink::close
or finish
methods. If it is
not, the copy will be aborted.

cx: &mut Context<'_>
) -> Poll<Result<u64, Error>>
[src]
self: Pin<&mut Self>,
cx: &mut Context<'_>
) -> Poll<Result<u64, Error>>
A poll-based version of finish
.
pub async fn finish(self: Pin<&mut Self>) -> Result<u64, Error>
[src]
Completes the copy, returning the number of rows inserted.
The Sink::close
method is equivalent to finish
, except that it does not return the
number of rows.
