Trait amethyst::ecs::storage::UnprotectedStorage

pub trait UnprotectedStorage<T>: TryDefault {
    unsafe fn clean<B>(&mut self, has: B)
    where
        B: BitSetLike;
    unsafe fn get(&self, id: u32) -> &T;
    unsafe fn get_mut(&mut self, id: u32) -> &mut T;
    unsafe fn insert(&mut self, id: u32, value: T);
    unsafe fn remove(&mut self, id: u32) -> T;

    unsafe fn drop(&mut self, id: u32) { ... }
}

Used by the framework to quickly join components.

Required Methods

unsafe fn clean<B>(&mut self, has: B) where
    B: BitSetLike, 

Clean the storage given a bitset with bits set for valid indices. Allows us to safely drop the storage.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

unsafe fn get(&self, id: u32) -> &T

Tries reading the data associated with an Index. This is unsafe because the external set used to protect this storage is absent.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

unsafe fn get_mut(&mut self, id: u32) -> &mut T

Tries mutating the data associated with an Index. This is unsafe because the external set used to protect this storage is absent.

unsafe fn insert(&mut self, id: u32, value: T)

Inserts new data for a given Index.

unsafe fn remove(&mut self, id: u32) -> T

Removes the data associated with an Index.

Provided Methods

unsafe fn drop(&mut self, id: u32)

Drops the data associated with an Index.
