Enum TransitionError 

#[non_exhaustive]
pub enum TransitionError {
    InvalidTransition {
        source: EditorialState,
        target: EditorialState,
    },
    InsufficientRole {
        role: EditorialRole,
        source: EditorialState,
        target: EditorialState,
    },
}

Error returned when a state transition is rejected.

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.

InvalidTransition

The state machine does not permit a direct jump.

Fields

source: EditorialState

target: EditorialState

InsufficientRole

The actor’s role is insufficient for the requested transition.

Fields

role: EditorialRole
