Expand description

Track reason for in-band or out-of-band cursor termination.

Variants§

§

SourceExhausted(CursorResultContinuation)

The underlying scan, irrespective of any limit, has reached the end (in-band).

If the cursor reaches return limit and exhausts the source at the same time, then return limit is returned.

§

ReturnLimitReached(CursorResultContinuation)

The limit on the number of items to return was reached (in-band).

If the cursor reaches return limit and exhausts the source at the same time, then return limit is returned.

§

TimeLimitReached(CursorResultContinuation)

The limit on the amount of time that a scan can take was reached (out-of-band).

§

ByteLimitReached(CursorResultContinuation)

The limit on the number of bytes to scan was reached (out-of-band).

§

KeyValueLimitReached(CursorResultContinuation)

The limit on the number of key-values to scan was reached (out-of-band).
