#[non_exhaustive]pub enum Error {
IllegalAction {
player: PlayerId,
},
NotActive {
player: PlayerId,
},
}Expand description
Errors returned by the engine’s checked entry points.
The in-place apply primitive assumes a legal action and does not return
errors; these surface from checked helpers such as apply_cloned, which
validate before mutating. More variants may be added, so match with a
wildcard arm.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
IllegalAction
The action is not legal for player in the current state.
NotActive
player is not among the active players owed a decision right now.
