Constant lmdb_rs::core::EnvCreateNoLock

pub const EnvCreateNoLock: EnvCreateFlags = EnvCreateFlags{bits: ffi::MDB_NOLOCK,}

Don't do any locking. If concurrent access is anticipated, the caller must manage all concurrency itself. For proper operation the caller must enforce single-writer semantics, and must ensure that no readers are using old transactions while a writer is active. The simplest approach is to use an exclusive lock so that no readers may be active at all when a writer begins.
