Struct legion::storage::EntityLayout

source · [−]

pub struct EntityLayout { /* private fields */ }

Expand description

Describes the component types which are attached to an entity.

Implementations

source

impl EntityLayout

source

pub fn new() -> Self

Constructs a new entity layout.

source

pub fn register_component<T: Component>(&mut self)

Adds a new component to the layout.

source

pub unsafe fn register_component_raw(
 &mut self,
 type_id: ComponentTypeId,
 f: fn() -> Box<dyn UnknownComponentStorage>
)

Adds a new component to the layout.

Safety

The storage returned from the storage constructor function must be capable of storing the component type identified by type_id.

source

pub fn component_types(&self) -> &[ComponentTypeId ]

Returns a slice of component type IDs for the components inside the layout.

source

pub fn has_component<T: Component>(&self) -> bool

Returns true if the layout contains the given component type.

source

pub fn has_component_by_id(&self, type_id: ComponentTypeId) -> bool

Returns true if the layout contains the given component type.

Blanket Implementations

source

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

source

pub fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source

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

const: unstable · source

pub fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source

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

const: unstable · source

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

Mutably borrows from an owned value. Read more

source

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

source

pub fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

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. Read more

source

pub fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

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

source

pub 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. Read more

source

pub 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. Read more

source

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

source

pub fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send + 'static>

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

source

impl<T> From<T> for T

const: unstable · source

pub fn from(t: T) -> T

Returns the argument unchanged.

source

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

const: unstable · source

pub fn into(self) -> U

Calls U::from(self).

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

source

impl<T> ToOwned for T where
T: Clone,

type Owned = T

The resulting type after obtaining ownership.

source

pub fn to_owned(&self) -> T

Creates owned data from borrowed data, usually by cloning. Read more

source

pub fn clone_into(&self, target: &mut T)

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

Uses borrowed data to replace owned data, usually by cloning. Read more

source

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

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source

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

Performs the conversion.

source

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

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

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

Performs the conversion.
