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.
