Enum sfsm::SfsmError

#[non_exhaustive]
pub enum SfsmError {
    Internal,
}

An error type that will be returned by the state machine if something goes wrong.

Specifically, when the state machine gets stuck in a state due to an internal error. The state machine is designed in a way where this should not happen, so this can largely be ignored. It is used in situations that are other wise hard to avoid without a panic!. It might be extended in the future to contains custom error codes generated from the states themselves

Variants (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.

Internal

Returned if the state machine gets stuck due to an internal error or if the state machine has not been started before stepping.
