Trait ToOwning 

pub trait ToOwning {
    type Owning;

    // Required method
    fn to_owning(&self) -> Self::Owning;
}

A generalization of ToOwned.

ToOwning is weaker than ToOwned because there is no constraint of Owning : Borrow<Self> as there is on ToOwned::Owned. Thus, ToOwning represents a type which can be converted from a reference into a related type that owns its contents, but unlike ToOwned doesn’t necessarily let you get a reference to the original type back out.

ToOwning has a blanket implementation for T where T : ToOwned, wherein Owning = Owned and to_owning = to_owned. User-defined types which implement ToOwning but not ToOwned typically should do so by calling .to_owning() on all their fields.

Required Associated Types

type Owning

The resulting type after obtaining ownership of self’s contents.

Required Methods

fn to_owning(&self) -> Self::Owning

Creates an object which owns its contents from one which borrows them.
