Module errors 

All possible errors that can occur when parsing the input. These errors should be returned to a front-end for handling display to the user.

All errors have Display implemented for them, so they can be easily serialized to a string.

Structs

CantPick

Error returned when the player tries to pick up an item marked as cant_pick.

EmptyInput

Error returned when trying to process an empty input. The front-end should handle this scenario, but this error is provided as a convenience.

InvalidAction

Error returned when the action is invalid

InvalidDirection

Error returned when the parser tries to access an invalid direction. This will likely be an issue in the configuration passed to nightrunner_lib when initializing the parser.

InvalidEvent

Examples

InvalidMovement

InvalidNarrative

InvalidRoom

Error returned when the parser tries to access an invalid room. This will likely be an issue in the configuration passed to nightrunner_lib when initializing the parser.

InvalidSubject

Error returned when the parser tries to access an invalid subject. This will likely be an issue in the configuration passed to nightrunner_lib when initializing the parser.

InvalidVerb

NoRoom

Error returned when no room is found while parsing the action.

ParsingRoomText
