Struct ResourcesSync

Source

pub struct ResourcesSync<'a> { /* private fields */ }

Expand description

Provides a thread-safe handle to the Resources container.

Only allows access to Send / Sync resources.

Implementations§

Source §

impl<'a> ResourcesSync<'a>

Source

pub fn get<T: Resource + Sync>(&self) -> Result<Ref<'_, T>, AccessError>

Returns an immutable reference to the stored T, if it exists.

§Errors

Returns AccessError::NoSuchResource if an instance of type T does not exist.
Returns AccessError::AlreadyBorrowed if there is an existing mutable reference to T.

Source

pub fn get_mut<T: Resource + Send>(&self) -> Result<RefMut<'_, T>, AccessError>

Returns an immutable reference to the stored T, if it exists.

§Errors

Returns AccessError::NoSuchResource if an instance of type T does not exist.
Returns AccessError::AlreadyBorrowed if there is an existing reference to T.

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

Source §

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.

Source §

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.

Source §

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.

Source §

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.

where T: Any + Send + Sync,

Source §

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.

Source §

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

Source §

type Error = Infallible

Performs the conversion.

Source §

impl<T, U> TryInto for T
where U: TryFrom<T>,

Source §

type Error = >::Error

The type returned in the event of a conversion error.

Source §

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
