Struct specs::storage::BTreeStorage

pub struct BTreeStorage<T>(_);

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<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.

Important traits for &'a mut W

impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

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.

Important traits for &'a mut W

impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

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.
