Trait cfx_storage::utils::WrappedCreateFrom

pub trait WrappedCreateFrom<FromType, ToType> {
    // Required method
    fn take(x: FromType) -> ToType;

    // Provided method
    fn take_from(dest: &mut ToType, x: FromType) { ... }
}

The purpose of this trait is to create a new value of a passed object, when the passed object is the value, simply move the value; when the passed object is the reference, create the new value by clone. Other extension is possible.

The trait is used by ChildrenTable and slab.

Required Methods

fn take(x: FromType) -> ToType

Provided Methods

fn take_from(dest: &mut ToType, x: FromType)

Unoptimized default implementation.
