Structs

• DataContext
  A partial result of a Trustfall query within the interpreter defined in this module.
• DynamicallyResolvedValue
  Indicates that a property’s value is dependent on another value in the query.
• EdgeInfo
  Information about an edge that is being resolved as part of a query.
• InterpretedQuery
• NeighborInfo
  Information about a neighboring vertex. Implements VertexInfo.
• QueryInfo
  Contains overall information about the query being executed, such as its outputs and variables.
• Range
  A range of values. Both its endpoints may be included or excluded in the range, or unbounded.
• RequiredProperty
  Represents a required property of a specific vertex
• ResolveEdgeInfo
  Enables adapter optimizations by showing how a query uses a particular edge.
• ResolveInfo
  Enables adapter optimizations by showing how a query uses a vertex. Implements VertexInfo.

Enums

• CandidateValue
  Candidate values for the value of a vertex property.

Traits

• Adapter
  Trustfall data providers implement this trait to enable querying their data sets.
• AsVertex
  Attempt to dereference a value to a &V, returning None if the value did not contain a V.
• Cast
  Allow bidirectional conversions between a type V and the type implementing this trait.
• Typename
  Accessor method for the __typename special property of Trustfall vertices.
• VertexInfo
  Information about what the currently-executing query needs at a specific vertex.

Type Aliases

• ContextIterator
  An iterator of query contexts: bookkeeping structs we use to build up the query results.
• ContextOutcomeIterator
  Iterator of (context, outcome) tuples: the output type of most resolver functions.
• VertexIterator
  An iterator of vertices representing data points we are querying.
