Struct RingElementWrapper

pub struct RingElementWrapper<R>
where
    R: RingStore,
{ /* private fields */ }

Stores a ring element together with its ring, so that ring operations do not require explicit mention of the ring object. This can be used both for convenience of notation (i.e. use a + b instead of ring.add(a, b)) and might also be necessary when e.g. storing elements in a set.

Examples

let ring = DensePolyRing::new(StaticRing::<i64>::RING, "X");
let x = RingElementWrapper::new(&ring, ring.indeterminate());
println!("The result is: {}", x.clone() + x.clone() * x);
// instead of
let x = ring.indeterminate();
println!("The result is: {}", ring.format(&ring.add(ring.mul(ring.clone_el(&x), ring.clone_el(&x)), ring.clone_el(&x))));

You can also retrieve the wrapped element

let ring = DensePolyRing::new(StaticRing::<i64>::RING, "X");
let x = RingElementWrapper::new(&ring, ring.indeterminate());
assert_el_eq!(&ring, ring.add(ring.mul(ring.clone_el(&x), ring.clone_el(&x)), ring.clone_el(&x)), (x.clone() + x.clone() * x).unwrap());

Implementations

impl<R: RingStore> RingElementWrapper<R>

pub const fn new(ring: R, element: El<R>) -> Self

Creates a new RingElementWrapper wrapping the given element of the given ring.

pub fn pow(self, power: usize) -> Self

Raises the stored element to the given power.

Consider using RingElementWrapper::pow_ref() if you don’t want to move the element.

pub fn pow_ref(&self, power: usize) -> Self

where R: Clone,

Raises the stored element to the given power.

pub fn unwrap(self) -> El<R>

Returns the stored element.

pub fn unwrap_ref(&self) -> &El<R>

Returns the stored element as reference.

pub fn parent(&self) -> &R

Returns a reference to the ring that this element belongs to.
