Struct LifecyclePollingNode 

pub struct LifecyclePollingNode { /* private fields */ }

Standalone lifecycle state machine for no_std environments.

Uses function pointers instead of boxed closures. Does not wrap a NodeHandle — the user manages the node separately.

Example

fn on_configure() -> TransitionResult {
    // Initialize hardware...
    TransitionResult::Success
}

let mut lifecycle = LifecyclePollingNode::new();
lifecycle.register_on_configure(on_configure);
lifecycle.configure()?;

Implementations

impl LifecyclePollingNode

pub const fn new() -> LifecyclePollingNode

Create a new standalone lifecycle state machine.

Starts in the Unconfigured state.

pub const fn state(&self) -> LifecycleState

Get the current lifecycle state.

pub fn trigger_transition( &mut self, transition: LifecycleTransition, ) -> Result<LifecycleState, LifecycleError>

Trigger a lifecycle transition.

pub fn configure(&mut self) -> Result<LifecycleState, LifecycleError>

Convenience: configure (Unconfigured -> Inactive)

pub fn activate(&mut self) -> Result<LifecycleState, LifecycleError>

Convenience: activate (Inactive -> Active)

pub fn deactivate(&mut self) -> Result<LifecycleState, LifecycleError>

Convenience: deactivate (Active -> Inactive)

pub fn cleanup(&mut self) -> Result<LifecycleState, LifecycleError>

Convenience: cleanup (Inactive -> Unconfigured)

pub fn shutdown(&mut self) -> Result<LifecycleState, LifecycleError>

Convenience: shutdown from the current state.

pub fn bring_up(&mut self) -> Result<LifecycleState, LifecycleError>

Convenience: configure then activate (stops on failure).

pub fn register_on_configure(&mut self, cb: fn() -> TransitionResult)

Register a callback for the configure transition.

pub fn register_on_activate(&mut self, cb: fn() -> TransitionResult)

Register a callback for the activate transition.

pub fn register_on_deactivate(&mut self, cb: fn() -> TransitionResult)

Register a callback for the deactivate transition.

pub fn register_on_cleanup(&mut self, cb: fn() -> TransitionResult)

Register a callback for the cleanup transition.

pub fn register_on_shutdown(&mut self, cb: fn() -> TransitionResult)

Register a callback for the shutdown transition.

pub fn register_on_error(&mut self, cb: fn() -> TransitionResult)

Register a callback for the error transition (error recovery).

Trait Implementations

impl Default for LifecyclePollingNode

fn default() -> LifecyclePollingNode

Returns the “default value” for a type.
