Struct oxygengine_core::ecs::storage::VecStorage

pub struct VecStorage<T>(_);

Vector storage. Uses a simple Vec. Supposed to have maximum performance for the components mostly present in entities.

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

Trait Implementations

impl<T> Default for VecStorage<T>

pub fn default() -> VecStorage<T>

Returns the “default value” for a type.

impl<T> UnprotectedStorage<T> for VecStorage<T>

pub 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.

pub 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.

pub 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.

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

Inserts new data for a given Index.

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

Removes the data associated with an Index.

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

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.
