Struct specs::TrackedStorage

pub struct TrackedStorage<C, S = DenseVecStorage<C>> { /* fields omitted */ }

Storage which tracks changes.

Methods

impl<C, S> TrackedStorage<C, S> where
    C: Clone,
    S: UnprotectedStorage<C>, 

pub fn change_events(&self) -> &[Change]

Returns a slice for all change events. The elements are in entity order, that means the Change for entity with id 5 will be the 6th element of this slice.

pub unsafe fn reset(&mut self, set: &BitSet)

Resets the TrackedStorage.

impl<C, S> TrackedStorage<C, S> where
    C: Clone + PartialEq,
    S: UnprotectedStorage<C>, 

pub unsafe fn maintain(&mut self, set: &BitSet)

Maintains the TrackedStorage

Trait Implementations

impl<C, S> Default for TrackedStorage<C, S> where
    S: Default, 

fn default() -> Self

Returns the "default value" for a type.

impl<C, S> UnprotectedStorage<C> for TrackedStorage<C, S> where
    C: Clone,
    S: UnprotectedStorage<C>, 

unsafe fn clean<F>(&mut self, f: F) where
    F: Fn(Index) -> bool, 

Clean the storage given a check to figure out if an index is valid or not. Allows us to safely drop the storage.

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

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 C

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, value: C)

Inserts new data for a given Index.

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

Removes the data associated with an Index.
