Trait Append

pub trait Append: Sized + Clear {
    // Required method
    fn append(&mut self, val: &mut Self);
}

A trait for moving data from one collection into another without freeing resources.

Conceptually, an append is equivalent to a push, with the caveat that the data is “moved out” of the pushed collection instead of being consumed. This allows reuse of the pushed collection’s resources.

Required Methods

fn append(&mut self, val: &mut Self)

Moves data out of val and into this collection.

Invoking this method should make val empty without freeing any resources. Any data that would be pushed out of self should be retained in val.

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.
