Trait Factory 

pub trait Factory<M>: Sized {
    // Required method
    fn definition() -> M;

    // Provided method
    fn make_many(count: usize) -> Vec<M> { ... }
}

A model factory. Generates randomized fake instances of M for tests/dev.

Mirrors Laravel’s Post::factory()->count(50)->create(). The definition() method returns a single random instance; make_many() / create_many() generate batches.

Required Methods

fn definition() -> M

Generate one random in-memory instance.

Provided Methods

fn make_many(count: usize) -> Vec<M>

Generate count random in-memory instances (not persisted).

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.
