Important traits for Range<A>

impl<A> Iterator for Range<A> where
    A: Step,  type Item = A;

Returns the valid range as a x..y range.

If x and y are equal, the range is full, not empty.

Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Scalar

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

Formats the value using the given formatter.

impl Eq for Scalar

fn assert_receiver_is_total_eq(&self)

impl Hash for Scalar

fn hash<__H>(&self, state: &mut __H) where     __H: Hasher,

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].

impl PartialEq<Scalar> for Scalar

fn eq(&self, other: &Scalar) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Scalar) -> bool

This method tests for !=.

impl<'a> HashStable<StableHashingContext<'a>> for Scalar

fn hash_stable<W: StableHasherResult>(     &self,     hcx: &mut StableHashingContext<'a>,     hasher: &mut StableHasher<W> )
