The name of a node (without path information)
Constructors
| NodeName | |
Fields
| |
The user-defined path of the node in the hierarchical representation of the graph.
Constructors
| NodePath | |
Fields | |
The unique ID of a node. It is based on the parents of the node and all the relevant intrinsic values of the node.
Constructors
| NodeId | |
Fields | |
The name of a field in a sql structure This structure ensures that proper escaping happens if required. TODO: prevent the constructor from being used, it should be checked first.
Constructors
| FieldName | |
Fields

A path to a nested field an a sql structure. This structure ensures that proper escaping happens if required.

catNodePath :: NodePath -> Text Source #
The concatenated path. This is the inverse function of fieldPath.
fieldName :: Text -> Either String FieldName Source #
A safe constructor for field names that fixes all the issues relevant to SQL escaping TODO: proper implementation
unsafeFieldName :: HasCallStack => Text -> FieldName Source #
Constructs the field name, but will fail if the content is not correct.
nullFieldPath :: FieldPath -> Bool Source #
