Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 1234]

▼NInfohazard
▼NHyperNav
▼NEditor
CFast3DArray	A data structure equivalent to a three-dimensional int array (int[,,]), but more efficient.
CMarchingCubesCavityTables	Tables for determining which cubes and combinations of cubes from the Marching Cubes algorithm will produce concave results.
CMarchingCubesTables	Tables used in the Marching Cubes algorithm.
CMultiRegionMeshInfo	A struct used to store mesh data of an in-progress volume mesh.
CNavEditorUtility	Utility functions used internally, but you can use them too, I mean I'm not your boss.
CNavVolumeBakeProgress	Represents current bake state of a volume, including progress fraction and current operation display name.
CNavVolumeBakingUtil	Contains all the code needed to generate the data for a NavVolume.
CNavVolumeEditor	Custom editor for Infohazard.HyperNav.NavVolume.
CNavVolumeExternalLinkUtil	Utilities for generating the external links of NavVolumes.
CThreadSafeIncrementor	A value that can be incremented, decremented, or added to in a thread safe way.
▼NJobs
CAvoidanceJob	Job that calculates the IAvoidanceAgent.AvoidanceVelocity of all IAvoidanceAgents.
CNativeAvoidanceObstacleData	Represents one obstacle (which may be an agent) in the avoidance system.
CNativeBounds	A native-friendly of a bounding box.
CNativeHeap	An implementation of a Min Heap that can be used with jobs and Burst.
CNativeMathUtility	Provides math operations that are compatible with Burst.
CNativeNavExternalLinkData	The native-friendly data representing a connection from one region to another region in another volume.
CNativeNavHit	A native-friendly representation of a navigation query result.
CNativeNavInternalLinkData	The native-friendly data representing a connection from one region to another region in the same volume.
CNativeNavRegionData	The native-friendly data representing a single region in a NavVolume.
CNativeNavVolumeData	The baked data of a NavVolume, converted to a form compatible with Burst.
CNativeNavWaypoint	A structure used by the navigation job to return the waypoints of a path.
CNativePlane	A plane constructed using native math types.
CNativeRay	A ray constructed using native math types.
CNativeRaycastElement	A single raycast in a NavMultiRaycastJob.
CNavMultiRaycastJob	Job that performs multiple raycasts in one or more NavVolumes in parallel.
CNavPathJob	Burst-compatible job used to find a HyperNav path.
CNavRaycastJob	Job that performs a single raycast in a NavVolume.
CPendingPathNode	A discovered node in a pending path, which serves as a key into the dictionary of per-node discovered info.
CSplineProjectJob	Job used to find the parameter along a spline that is nearest to the given point.
CUnsafeArrayPtr	This is a simple wrapper for unmanaged memory which bypasses Unity's safety checks. This allows arrays to be nested in other arrays (or in structs contained in arrays). Note that you must keep a reference to the original NativeArray, or Unity will detect a memory leak.
CVisitedNodeInfo	The information that has been discovered about a node during pathfinding, which is stored in a table.
CAvoidance	Static container that keeps track of all avoidance agents and obstacles.
CAvoidanceAgent	Base implementation of IAvoidanceAgent that should work in most scenarios.
CAvoidanceManager	Handles calculating the avoidance velocities for all IAvoidanceAgents.
CAvoidanceObstacleBase	Base class for obstacles that are not expected to perform avoidance, but are avoided by agents.
CEdge	Represents the indices of an edge (two connected vertices) in an indexed mesh.
CIAvoidanceAgent	Interface for objects that both can be avoided and themselves avoid other obstacles using the avoidance system.
CIAvoidanceObstacle	Interface for objects that can be avoided using the avoidance system.
▼CNavAgent	A script that can be used to calculate paths by any entity that needs to use HyperNav for navigation.
CPropNames	This is used to refer to the names of private fields in this class from a custom Editor.
CNavDataInternalPointers	References to the NativeArrays allocated for a NativeNavVolumeData.
CNavExternalLinkData	A connection from one region to another region in another volume.
CNavHit	Structure that is used to report the nearest point on a NavVolume to a query.
CNavInternalLinkData	A connection from one region to another region in the same volume.
CNavPath	A completed, valid path.
▼CNavPathfinder	A script used to calculate HyperNav paths.
CPropNames	This is used to refer to the names of private fields in this class from a custom Editor.
CNavRegionBoundPlane	A plane forming one of the boundaries of a region.
CNavRegionData	The serialized data representing a single region in a NavVolume.
CNavUtil	Contains utility methods for working with HyperNav navigation.
▼CNavVolume	A volume of space in which HyperNav pathfinding can occur.
CPropNames	This is used to refer to the names of private fields in this class from a custom Editor.
CNavVolumeData	The baked data of a NavVolume, saved as an asset.
CNavWaypoint	A waypoint in a completed path.
CRigidbodyAvoidanceObstacle	An IAvoidanceObstacle that gets its IAvoidanceObstacle.InputVelocity from a Rigidbody.
CSimpleAvoidanceObstacle	An IAvoidanceObstacle that gets its IAvoidanceObstacle.InputVelocity by measuring its position/time delta.
CSplineNavAgent	A script that can be used to calculate smooth paths by any entity that needs to use HyperNav for navigation.
CSplinePath	A spline specialized for path following, created with a NavPath.
CSplinePoint	Represents a point on a spline and the segment that starts with it.
CTriangle	Represents the indices of a triangle (three vertices by a face) in an indexed mesh.
