Package reltest provides tools for testing the rel package.

And constructs a clause represents a set of clauses which should be taken in conjunction and exist so that go functions can be written to return a single clause without needing to get involved in appending to a slice of clauses.

AttrType maps the Attr to the provided type.

EntityAttr defines a mapping of selector[s] to Attr for an entity.

EntityAttrOneOf defines a mapping of selector[s] to Attr for an entity.

EntityMapping is used to specify how fields of a type are mapped to Attrs.

Filter is used to construct a clause which runs an arbitrary predicate over variables.

MustSchema is like NewSchema but any errors result in a panic.

NewDatabase constructs a new Database with the specified indexes.

NewQuery construct a new query with the provided clauses forming the conjunction of constraints on the results of the query when it is evaluated against a database.

NewSchema constructs a new schema from mappings.

Blank is a special variable which, when used, means that the value should be bound to something.

Self is an attribute which stores the variable itself.

Type is an attribute which stores a value's type.

Database is a data structure for indexing entities.

Index defines an index over the stored entities.

IndexWhere is a partial index predicate for a rel index.

Query searches for sets of entities which uphold a set of constraints.

RuleDef describes a rule.

Schema defines a mapping of entities to their attributes and decomposition.

Attr is used to define a property of entities.

Clause is the basic building block of a query.

EntityMappingOption is used to build an EntityMapping.

Result represents A setting of entities which fulfills the constraints of its corresponding query.

SchemaOption is used to construct a schema.

Clauses exists to handle flattening of a slice of clauses before marshaling.

ResultIterator is used to iterate results of A query.

Var is a variable name.
