Struct specs::DenseVecStorage

[+] Show declaration

pub struct DenseVecStorage<T> { /* fields omitted */ }

[−] Expand description

Dense vector storage. Has a redirection 2-way table between entities and components, allowing to leave no gaps within the data.

Note that this only stores the data (T) densely; indices to the data are stored in a sparse Vec.

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.

fn default() -> Self[−]

Returns the "default value" for a type.
