Crate indradb

IndraDB: a graph datastore.

IndraDB is broken up into a library and an application. This is the library, which you would use if you want to create new datastore implementations, or plug into the low-level details of IndraDB. For most use cases, you can use the application, which exposes an API and scripting layer.

Modules

• util
  Utility functions. These are public because they may be useful for crates that implement Datastore.

Macros

• ijson
  Similar to serde_json::json!, this allows you to create JSON literals. It’s called ijson to not conflict with serde_json::json!.

Structs

• AllEdgeQuery
  Gets all edges.
• AllVertexQuery
  Gets all vertices.
• CountQuery
  Counts the number of items returned from a query.
• Database
  The IndraDB database.
• Edge
  An edge.
• EdgeProperties
  An edge with properties.
• EdgeProperty
  Represents an edge property.
• EdgeWithPropertyPresenceQuery
  Gets edges with or without a given property.
• EdgeWithPropertyValueQuery
  Gets edges with a property equal to a given value.
• Identifier
  A string that must be less than 256 characters long, and can only contain letters, numbers, dashes and underscores. This is used for vertex and edge types, as well as property names.
• IncludeQuery
  Includes the results of a query in output.
• Json
  Wraps serde_json::Value in an Arc to make it more cheaply cloneable, as well as implements extra traits useful for datastore storage and querying.
• MemoryDatastore
  An in-memory datastore.
• NamedProperty
  A property.
• PipePropertyQuery
  Returns the properties associated with a vertex or edge.
• PipeQuery
  Gets the vertices associated with edges, or edges associated with vertices.
• PipeWithPropertyPresenceQuery
  Gets vertices or edges with or without a property.
• PipeWithPropertyValueQuery
  Gets vertices or edges with a property equal to a given value.
• RangeVertexQuery
  Gets a range of vertices.
• SpecificEdgeQuery
  Gets a specific set of edges.
• SpecificVertexQuery
  Gets a specific set of vertices.
• Vertex
  A vertex.
• VertexProperties
  A vertex with properties.
• VertexProperty
  Represents a vertex property.
• VertexWithPropertyPresenceQuery
  Gets vertices with or without a given property.
• VertexWithPropertyValueQuery
  Gets vertices with a property equal to a given value.

Enums

• BulkInsertItem
  An item to insert, as part of a bulk insert request.
• EdgeDirection
  Specifies what kind of items should be piped from one type of query to another.
• Error
  An error triggered by the datastore.
• Query
  A query to get a set of values from the database.
• QueryOutputValue
  Value(s) returned from a query.
• ValidationError
  A validation error

Traits

• CountQueryExt
• Datastore
  Specifies a datastore, which provides datastore transaction implementations to the database.
• QueryExt
  Extension trait containing common functions for all query structs.
• Transaction
  Specifies a datastore transaction, which contains nearly all of the datastore implementation-specific logic.

Type Definitions

• DynIter
  A dynamic iterator over results, which are commonly employed as transaction return types.
• Result
  A result that might be an Error.
• ValidationResult
  A result that might be a ValidationError.
