pub struct Resources { /* private fields */ }

Provides a shared Resource container.

Implementations

impl Resources

pub fn insert<T: Resource>(&mut self, resource: T)

Inserts a Resource of type T into the store.

If an instance of T already exists, it is quietly replaced with the new instance.

Call Resources::remove() first, if you want to retrieve the existing instance.

pub fn remove<T: Resource>(&mut self) -> Option<T>

Removes the instance of type T from the store, if it exists.

pub fn sync(&mut self) -> ResourcesSync<'_>

pub fn get<T: Resource>(&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.

pub fn get_mut<T: Resource>(&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.
