Struct cop::Signed

pub struct Signed<T>(pub bool, pub T);

Wrapper around an object to store a sign (+/-) along it.

This is used to store whether a literal is negated (-) or not (+).

Tuple Fields

0: bool

1: T

Implementations

impl<T: Clone> Signed<&T>

pub fn cloned(self) -> Signed<T>

Clone the contents of the signed object.

impl<T> Signed<T>

pub fn map<U>(self, f: &mut impl FnMut(T) -> U) -> Signed<U>

Apply a function to the contained object.

pub fn is_sign_positive(&self) -> bool

Return true if the sign is positive.

pub fn is_sign_negative(&self) -> bool

Return true if the sign is negative.

Trait Implementations

impl<T: Clone> Clone for Signed<T>

fn clone(&self) -> Signed<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Signed<T>

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

Formats the value using the given formatter.

impl<T: Display> Display for Signed<T>

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

Formats the value using the given formatter.

impl<T> From<T> for Signed<T>

fn from(x: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for Signed<T>

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl<T> Neg for Signed<T>

type Output = Signed<T>

The resulting type after applying the - operator.

fn neg(self) -> Self

Performs the unary - operation.

impl<T: PartialEq> PartialEq<Signed<T>> for Signed<T>

fn eq(&self, other: &Signed<T>) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
