Trait PrimaryKeyTrait 

pub trait PrimaryKeyTrait: IdenStatic + Iterable {
    type ValueType: IntoValueTuple + TryFromU64 + Clone + Debug + Send + Sync;

    // Required method
    fn auto_increment() -> bool;
}

The primary key of an entity, derived on the PrimaryKey enum.

Required Associated Types

type ValueType: IntoValueTuple + TryFromU64 + Clone + Debug + Send + Sync

The Rust type of the key: the field type for a single column, a tuple of field types for a composite key.

Required Methods

fn auto_increment() -> bool

Whether the database generates the key, as with INTEGER PRIMARY KEY.

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
