Struct DeathRecipient

Source 
#[repr(C)]
pub struct DeathRecipient { /* private fields */ }
Expand description

Rust wrapper around DeathRecipient objects.

The cookie in this struct represents an Arc<F> for the owned callback. This struct owns a ref-count of it, and so does every binder that we have been linked with.

Dropping the DeathRecipient will unlink_to_death any binders it is currently linked to.

Implementations§

Source§

impl DeathRecipient

Source

pub fn new<F>(callback: F) -> DeathRecipient
where F: Fn() + Send + Sync + 'static,

Create a new death recipient that will call the given callback when its associated object dies.

Trait Implementations§

Source§

impl Drop for DeathRecipient

Source§

fn drop(&mut self)

Executes the destructor for this type. Read more
Source§

impl Send for DeathRecipient

Safety: A DeathRecipient is a wrapper around AIBinder_DeathRecipient and a pointer to a Fn which is Sync and Send (the cookie field). As AIBinder_DeathRecipient is threadsafe, this structure is too.

Source§

impl Sync for DeathRecipient

Safety: A DeathRecipient is a wrapper around AIBinder_DeathRecipient and a pointer to a Fn which is Sync and Send (the cookie field). As AIBinder_DeathRecipient is threadsafe, this structure is too.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

Source§

fn from(t: T) -> T

Returns the argument unchanged.

Source§

impl<T, U> Into<U> for T
where U: From<T>,

Source§

fn into(self) -> U
