[−][src]Struct world_dispatcher::World

pub struct World { /* fields omitted */ }

Contains data indexed by type. World allows to dynamically enforce the rust rules of borrowing and ownership at runtime:

  • The same type cannot be borrowed immutably and mutably at the same time.
  • The same type cannot be borrowed mutably more than once at the same time.

Implementations

impl World[src]

pub fn initialize<T: Default + 'static>(&mut self)[src]

Initializes a resource to its default value. This is the only way to "insert" a resource.

It is suggested to use a macro to collect all the resources and initialize all of them.

pub fn get<T: 'static>(&self) -> Result<Ref<'_, T>, EcsError>[src]

Get an immutable reference to a resource by type. Will return an error if the type is:

  • Non initialized
  • Already borrowed mutably

pub fn get_mut<T: 'static>(&self) -> Result<RefMut<'_, T>, EcsError>[src]

Get a mutable reference to a resource by type. Will return an error if the type is:

  • Non initialized
  • Already borrowed immutably
  • Already borrowed mutably
