Attribute	A Mentat schema attribute has a value type and several other flags determining how assertions with the attribute are interpreted.
KnownEntid	An entid that's either already in the store, or newly allocated to a tempid. TODO: we'd like to link this in some way to the lifetime of a particular PartitionMap.
StructuredMap	A pull expression expands a binding into a structure. The returned structure associates attributes named in the input or retrieved from the store with values. This association is a `StructuredMap`.
ValueTypeSet

AttributeBitFlags	Bit flags used in `flags0` column in temporary tables created during search, such as the `search_results`, `inexact_searches` and `exact_searches` tables. When moving to a more concrete table, such as `datoms`, they are expanded out via these flags and put into their own column rather than a bit field.
Binding	The values bound in a query specification can be:
TypedValue	Represents a value that can be stored in a Mentat store.
ValueType	The attribute of each Mentat assertion has a :db/valueType constraining the value to a particular set. Mentat recognizes the following :db/valueType values.

now	Return the current time as a UTC `DateTime` instance with microsecond precision.

Represents one entid in the entid space.
