Constant lmdb::DUP_FIXED
[−]
pub const DUP_FIXED: DatabaseFlags=
DatabaseFlags{bits: MDB_DUPFIXED,}
This flag may only be used in combination with DUP_SORT
. This option tells
the library that the data items for this database are all the same size, which
allows further optimizations in storage and retrieval. When all data items are
the same size, the GET_MULTIPLE
and NEXT_MULTIPLE
cursor operations may be
used to retrieve multiple items at once.
