ceremonyclient/pebble/testdata/level_iter_seek

# Note that this test file uses a levelIterTestIter which combines a
# point iterator and a range-del iterator, returning both results in a
# single key:
#
#   <point-key>/<tombstone>#<point-seqnum,point-kind>

# Verify that SeekGE, SeekLT, Next, and Prev all pause at table
# boundaries in the presence of lower/upper bounds and range
# tombstones. Verify that SeekPrefixGE pauses at a table boundary in
# the presence of range tombstones.
