class	buffer <class ALLOCATOR, typename CAPACITY_POLICY> The chunk of data stored inside the buffer or located outside it.
struct	buffer_pair_spec <typename ALLOCATOR, typename CAPACITY_POLICY> A pair of buffer instances for a key and a value, with the same allocator and capacity policy; the buffer counterpart ofpair .
struct	buffer_tag Type tag for delivered buffer template classes.
class	cache_entry Cache entry for the transparent read-your-writes caching, see txn::get_cached() andmdbx_cache_get() .
class	cursor Unmanaged cursor.
class	cursor_managed Managed cursor.
struct	dangling_map_id Thrown on MDBX_DANGLING_DBI , i.e. a table handle refers to a non-existent table.
struct	db_corrupted Thrown on MDBX_CORRUPTED , i.e. the database is corrupted or an invalid data was detected.
struct	db_full Thrown on MDBX_MAP_FULL , i.e. the database is full and the environment cannot be extended.
struct	db_invalid Thrown on MDBX_INVALID , i.e. an invalid parameter was specified or the environment is already closed.
struct	db_too_large Thrown on MDBX_TOO_LARGE , i.e. the database is too large for the current process/environment.
struct	db_unable_extend Thrown on MDBX_UNABLE_EXTEND_MAPSIZE , i.e. the requested geometry change needs the mapping to be re-created but it could not be applied right now.
struct	db_version_mismatch Thrown on MDBX_VERSION_MISMATCH , i.e. the database was created by an incompatible version of libmdbx.
struct	db_wanna_write_for_recovery Thrown on MDBX_WANNA_RECOVERY , i.e. the database requires recovery usingmdbx_chk and/ormdbx_env_open_for_recovery() .
struct	default_capacity_policy The default capacity policy for the buffer class: rounds the allocated capacity and advises whether to grow, keep or shrink it.
struct	duplicated_lck_file Thrown on MDBX_DUPLICATED_LCK , i.e. the lock file was created in a manner that conflicts with the current process' state.

struct	max_readers_reached Thrown on MDBX_READERS_FULL , i.e. the environment's reader table is full.
struct	multivalue Thrown on MDBX_EMULTIVAL , i.e. the operation is not supported for the multi-value (dupsort) key.
