Trait IntoOption 

pub trait IntoOption<T>: Sized {
    // Required method
    fn into_option(self) -> T;
}

A trait for auto-wrapping a generic type T into Option<Y>, where Y can be inferred from context. (useful in macro helpers, such as NewDefaultV!)

Required Methods

fn into_option(self) -> T

Performs the conversion.

Dyn Compatibility

This trait is not dyn compatible.

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