Required Methods

fn first( &self, ) -> Result<Option<(AccessGuard<'_, K, SortKey<S>>, AccessGuard<'_, V>)>, StorageError>

fn last( &self, ) -> Result<Option<(AccessGuard<'_, K, SortKey<S>>, AccessGuard<'_, V>)>, StorageError>

fn range<'a, Q>( &self, range: impl RangeBounds<Q> + 'a, ) -> Result<Range<'_, K, V, SortKey<S>>, StorageError>

where K: Borrow<Q>, Q: Encode + ?Sized,

fn get<Q>(&self, key: &Q) -> Result<Option<AccessGuard<'_, V>>, StorageError>

where K: Borrow<Q>, Q: Encode + ?Sized,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
