NonSends

bevy_ecs::storage

Struct NonSends

pub struct NonSends { /* private fields */ }

Expand description

The backing store for all Resources stored in the World.

Implementations§

impl NonSends

pub fn len(&self) -> usize

The total amount of !Send data stored in the World

pub fn iter(&self) -> impl Iterator<Item = (ComponentId, &NonSendData)>

Iterate over all resources that have been initialized, i.e. given a ComponentId

pub fn is_empty(&self) -> bool

Returns true if there is no !Send data stored in the World, false otherwise.

pub fn get(&self, component_id: ComponentId) -> Option<&NonSendData>

Gets read-only access to some !Send data, if it exists.

pub fn clear(&mut self)

Clears all resources.

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

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

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

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

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

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

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

Converts &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)

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

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T> FromWorld for T
where T: Default,

fn from_world(_world: &mut World) -> T

Creates Self using default().

impl<T, W> HasTypeWitness<W> for T
where W: MakeTypeWitness<Arg = T>, T: ?Sized,

const WITNESS: W = W::MAKE

A constant of the type witness

impl<T> Identity for T
where T: ?Sized,

const TYPE_EQ: TypeEq<T, <T as Identity>::Type> = TypeEq::NEW

Proof that Self is the same type as Self::Type, provides methods for casting between Self and Self::Type.

type Type = T

The same type as Self, used to emulate type equality bounds (T == U) with associated type equality constraints (T: Identity<Type = U>).

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

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T> IntoResult<T> for T

fn into_result(self) -> Result<T, RunSystemError>

Converts this type into the system output type.

impl<A> Is for A
where A: Any,

fn is<T>() -> bool
where T: Any,

Checks if the current type “is” another type, using a TypeId equality comparison. This is most useful in the context of generic logic. Read more

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

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

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

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

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

Performs the conversion.
