Struct specs::DefaultVecStorage

pub struct DefaultVecStorage<T>(_);

Vector storage, like VecStorage, but allows safe access to the interior slices because unused slots are always initialized.

Requires the component to implement Default.

as_slice() and as_mut_slice() indices correspond to entity IDs. These can be compared to other DefaultVecStorages, to other VecStorages, and to Entity::id()s for live entities.

Trait Implementations

impl<T> Default for DefaultVecStorage<T>

fn default() -> Self

Returns the "default value" for a type.

impl<T> DistinctStorage for DefaultVecStorage<T>

impl<T> UnprotectedStorage<T> for DefaultVecStorage<T> where
    T: Default, 

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.

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

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

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

Inserts new data for a given Index.

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

Removes the data associated with an Index.

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

Drops the data associated with an Index. This is simply more efficient than remove and can be used if the data is no longer needed.
