Trait Identifiable 

pub trait Identifiable {
    type Key;

    const ID_COLUMN: &'static str;

    // Required method
    fn id(&self) -> Option<Self::Key>;
}

Trait for entities that have an identifiable key. This trait exposes the key type and column name so macros can introspect it.

Required Associated Constants

const ID_COLUMN: &'static str

The name of the primary key column in the database.

Required Associated Types

type Key

The type of the primary key (e.g., i64, Uuid).

Required Methods

fn id(&self) -> Option<Self::Key>

Returns a copy of the entity’s ID, if it has one.

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.
