Trait Producer 

pub trait Producer<T> {
    // Required method
    fn initialize(self) -> T;
}

For use with LazyLock.

This trait is implemented for FnOnce closures, so most users can just use that directly. However in case they need to name a type in the LazyLock, they can create a type that implements this trait instead.

Required Methods

fn initialize(self) -> T

Dyn Compatibility

This trait is dyn compatible.

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