Types

type FakeWriterAt

type FakeWriterAt struct {
	// contains filtered or unexported fields
}

FakeWriterAt represents a struct that provides the method WriteAt so it will satisfy interface io.WriterAt. It will ignore offset and therefore works like just io.Writer. AWS SDK is Using io.WriterAt because of concurrent download, so it can write at offset position (e.g. in middle of file). By disabling concurrent download we can safely ignore the offset argument because it will be downloaded sequentially.
