Result and error types used across all graph operations.

Enumeration Type Documentation

ErrorType

enum class cgrapht::ErrorType

strong

Error codes returned by graph operations.

All fallible graph operations return Result<T, ErrorType>. Check the error code via result.get_error() when result.is_ok() returns false.

Enumerator
INVALID_ARGUMENT	A supplied argument is invalid.
ABSENT_VERTEX	The referenced vertex ID does not exist in the graph.
ABSENT_EDGE	The referenced edge ID does not exist in the graph.
EDGE_ALREADY_EXISTS	An edge between the two vertices already exists.
VERTEX_NOT_FREE	The vertex cannot be removed because it still has incident edges.
UNKNOWN	An unexpected internal error occurred.
