Trait swipl::atom::AsAtom

pub trait AsAtom {
    // Required method
    fn as_atom(&self) -> Atom;

    // Provided method
    fn as_atom_ptr(&self) -> (atom_t, Option<Atom>) { ... }
}

Trait for types which can be turned into an Atom from a borrow.

Required Methods

fn as_atom(&self) -> Atom

Turn the borrowed object into an Atom.

The second argument ensures that this function is called in a context where atoms are allowed to be created.

Provided Methods

fn as_atom_ptr(&self) -> (atom_t, Option<Atom>)

Turn the borrowed object into an atom_t, and returns an allocation which will keep this atom_t valid as long as it is not dropped.

This allows code that takes an AsAtom to be a little bit smart about not cloning the underlying data, if the underlying data is already an atom.
