Struct specs::storage::DefaultVecStorage

source · [−]

pub struct DefaultVecStorage<T>(_);

Expand description

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. Read more

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. Read more

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. Read more

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. Read more

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

Inserts new data for a given Index. Read more

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

Removes the data associated with an Index. Read more

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

Drops the data associated with an Index. This could be used when a more efficient implementation for it exists than remove when the data is no longer needed. Defaults to simply calling remove. Read more
