Trait Extract 

pub trait Extract<A: Access<T>, T>:
    Access<T>
    + Sized
    + TryExtract<A, T> {
    // Required method
    fn extract(self) -> (A, <A as Access<T>>::RemainderFrom<Self>);
}

Trait for compile-time checked extraction from one access type to another.

Returns both the extracted value (in target access type) and the remainder.

Required Methods

fn extract(self) -> (A, <A as Access<T>>::RemainderFrom<Self>)

Extract a value into target type and remainder parts.

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.
