Struct FileLockStateMachine 

pub struct FileLockStateMachine { /* private fields */ }

State machine for FileLock workflow

Implementations

impl FileLockStateMachine

pub fn new() -> Self

Create a new state machine with initial state

pub fn from_state(state: FileLockState) -> Self

Create from an existing state

pub fn current_state(&self) -> FileLockState

Get the current state

pub fn can_transition(&self, transition: FileLockTransition) -> bool

Check if a transition is allowed from the current state

pub fn can_transition_with_role( &self, transition: FileLockTransition, role: &str, ) -> bool

Check if a transition is allowed for a given role

pub fn transition( &mut self, transition: FileLockTransition, ) -> Result<FileLockState, StateMachineError>

Apply a transition, returning the new state

pub fn transition_with_role( &mut self, transition: FileLockTransition, role: &str, ) -> Result<FileLockState, StateMachineError>

Apply a transition with role check

pub fn available_transitions(&self) -> Vec<FileLockTransition>

Get all available transitions from the current state

pub fn available_transitions_for_role( &self, role: &str, ) -> Vec<FileLockTransition>

Get all available transitions for a given role

pub fn transition_to_state( &mut self, target: FileLockState, ) -> Result<FileLockState, StateMachineError>

Attempt to transition directly to a target state.

Finds any transition that leads to the target state and applies it. Returns Err if no valid transition leads from current state to target.
