Trait DefaultGenerator 

pub trait DefaultGenerator: Sized {
    type Generator: Generator<Self> + 'static;

    // Required method
    fn default_generator() -> Self::Generator;
}

Trait for types that have a default generator.

This is used by derive macros to automatically generate values for fields.

Required Associated Types

type Generator: Generator<Self> + 'static

Required Methods

fn default_generator() -> Self::Generator

Dyn Compatibility

This trait is not dyn compatible.

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