Struct LifecycleHandle 

pub struct LifecycleHandle { /* private fields */ }

RAII handle that owns a component id and runs destroy+cleanup on drop.

The renderer creates one per mounted app and keeps it alive for the duration of the event loop so on_unmounted/before_destroy fire even when the loop exits via Drop rather than an explicit CloseRequested.

Implementations

impl LifecycleHandle

pub fn new() -> Self

Allocate a fresh component id and enter its registration context.

pub fn with_id(id: usize) -> Self

Wrap an existing id (the id is not re-entered into the current context; call set_current_component if hook registration is needed).

pub fn id(&self) -> usize

pub fn mount(&self)

Run mounted hooks once. Safe to call redundantly.

pub fn is_mounted(&self) -> bool

True once mount has been called.

Trait Implementations

impl Default for LifecycleHandle

fn default() -> Self

Returns the “default value” for a type.

impl Drop for LifecycleHandle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
