Trait ReadableOptionExt

pub trait ReadableOptionExt<T: 'static>: Readable<Target = Option<T>> {
    // Provided methods
    fn unwrap(&self) -> T
       where T: Clone { ... }
    fn as_ref(&self) -> Option<ReadableRef<'_, Self, T>> { ... }
}

An extension trait for Readable<Option> that provides some convenience methods.

Provided Methods

fn unwrap(&self) -> T

where T: Clone,

Unwraps the inner value and clones it.

fn as_ref(&self) -> Option<ReadableRef<'_, Self, T>>

Attempts to read the inner value of the Option.

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.
