// Required method
fn borrow_primary_key(&self) -> Self::BorrowedPrimaryKey<'_>;
}Expand description
Something whose primary key can be borrowed as a distinct type.
i.e. &str, &[u8], or a type with one or more borrowed fields.
Required Associated Types§
type BorrowedPrimaryKey<'a>: Copy + Send + Sync + Into<<Self as PrimaryKey>::PrimaryKey> where Self: 'a
Required Methods§
Sourcefn borrow_primary_key(&self) -> Self::BorrowedPrimaryKey<'_>
fn borrow_primary_key(&self) -> Self::BorrowedPrimaryKey<'_>
Borrow this entity’s primary key without copying any data.
This borrowed key has a lifetime tied to that of this entity.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
