Expand description

Extend an Entity with db-mutating operations which can be performed when provided with a transaction.

Required Methods§

Source

fn delete_borrowed<'life0, 'life1, 'async_trait, Q>( tx: &'life0 <Self as EntityDatabaseMutation<'a>>::Transaction, id: &'life1 Q, ) -> Pin<Box<dyn Future<Output = CryptoKeystoreResult<bool>> + Send + 'async_trait>>
where Self::PrimaryKey: Borrow<Q>, Q: KeyType + 'async_trait, Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete an entity by a borrowed form of its primary key.

The type signature here is somewhat complicated, but it breaks down simply: if our primary key is something like Vec<u8>, we want to be able to use this method even if what we have on hand is &[u8].

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.
