Detailed Description

Error handling strategy for pathfinding algorithms.

This file defines a consistent error handling approach across all pathfinding algorithms in the project.

Enumeration Type Documentation

strong

Error codes for pathfinding operations.

Consistent error codes across all pathfinding algorithms (A*, Dijkstra, etc.)

Enumerator
None	No error occurred.
InvalidCell	One or both cells are invalid (H3_NULL or failed isValidCell)
SameStartEnd	Start and end points are identical.
BlockedStartCell	Start cell is blocked by an obstacle.
BlockedEndCell	End cell is blocked by an obstacle.
NoPathFound	No path exists between start and end (disconnected graph)
ConversionError	Error converting between H3 resolutions.
CoordinateError	Error getting cell coordinates.
MaxIterations	Search exceeded maximum iteration limit.
InternalError	Internal algorithm error.
