Trait IntoOption

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

A type that can be converted into an Option<T>.

This trait exists to unify how Unwrapped abstracts implementations for Result and Option. In the future, if the standard library implements Into<Option<T>> for Result<T,E>, this trait can be removed.

Required Methods

fn into_option(self) -> Option<T>

Returns self as an option.
