Enum world_dispatcher::EcsError[−][src]

pub enum EcsError {
    NotInitialized,
    AlreadyBorrowed,
    DispatcherExecutionFailed(Vec<EcsError>),
    SystemError(Box<dyn Error + Send>),
}
Expand description

The types of errors a System can create.

Variants

NotInitialized
Expand description

A resource was not initialized in the World but the System tries to access it.

Usually, this means no dispatcher was used and World::initialize was not called.

AlreadyBorrowed
Expand description

The requested resource is already borrowed. This error is created if the System tries to read a resource that has already been mutably borrowed. It can also happen when trying to mutably borrow a resource that is already being read.

This error should not occur during normal use, as the dispatchers can recover easily.

DispatcherExecutionFailed(Vec<EcsError>)
Expand description

The execution of the dispatcher failed and returned one or more errors.

SystemError(Box<dyn Error + Send>)
Expand description

This variant is for user-defined errors. To create an error of this type easily, use the system_error! macro.

Blanket Implementations

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

pub fn type_id(&self) -> TypeId[src]

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T where
    T: ?Sized, [src]

pub fn borrow(&self) -> &T[src]

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T where
    T: ?Sized, [src]

pub fn borrow_mut(&mut self) -> &mut T[src]

Mutably borrows from an owned value. Read more

impl<T> Downcast for T where
    T: Any, [src]

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

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

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

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

pub fn as_any(&self) -> &(dyn Any + 'static)[src]

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

pub fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)[src]

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

impl<T> From<T> for T[src]

pub fn from(t: T) -> T[src]

Performs the conversion.

impl<T, U> Into<U> for T where
    U: From<T>, [src]

pub fn into(self) -> U[src]

Performs the conversion.

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

impl<T, U> TryInto<U> for T where
    U: TryFrom<T>, [src]

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

The type returned in the event of a conversion error.

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

Performs the conversion.
