Module mentat_db::types

Structs

Attribute	A Mentat schema attribute has a value type and several other flags determining how assertions with the attribute are interpreted.
DB	Represents the metadata required to query from, or apply transactions to, a Mentat store.
DateTime	ISO 8601 combined date and time with time zone.
Partition	Represents one partition of the entid space.
Schema	Represents a Mentat schema.
TxReport	A transaction report summarizes an applied transaction.
Utc	The UTC time zone. This is the most efficient time zone when you don't need the local time. It is also used as an offset (which is also a dummy type).

Enums

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.
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.

Traits

TransactableValue

The transactor is tied to edn::ValueAndSpan right now, but in the future we'd like to support TypedValue directly for programmatic use. TransactableValue encapsulates the interface value types (i.e., values in the value place) need to support to be transacted.

Type Definitions

AVMap	Map [a v] pairs to existing entids.
AVPair	A pair [a v] in the store.
AttributeSet
Entid	Represents one entid in the entid space.
PartitionMap	Map partition names to Partition instances.
