Enum AssignOr 

pub enum AssignOr<M>
where
    M: Monoid,
    <M as Monoid>::Set: Clone,
{
    Assign(<Assign<<M as Monoid>::Set> as Monoid>::Set),
    Other(<M as Monoid>::Set),
}

Extends any Monoid with = operation.

Variants

Assign(<Assign<<M as Monoid>::Set> as Monoid>::Set)

= operation

Other(<M as Monoid>::Set)

the associative binary operation of M, which is a Monoid.

Trait Implementations

impl<M> Clone for AssignOr<M>

where M: Monoid, <M as Monoid>::Set: Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M> Debug for AssignOr<M>

where M: Monoid, <M as Monoid>::Set: Debug + Clone,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<M> Monoid for AssignOr<M>

where M: Monoid, <M as Monoid>::Set: Clone,

const IS_COMMUTATIVE: bool = false

If Self::combine is commutative, some operations can be optimized.

type Set = AssignOr<M>

The set of the monoid.

fn identity() -> Self::Set
