BTreeMap-based storage.

Trait Implementations

impl<T> Default for BTreeStorage<T>

fn default() -> Self

Returns the "default value" for a type.

impl<T> UnprotectedStorage<T> for BTreeStorage<T>

unsafe fn clean<F>(&mut self, _: 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) -> &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.
