Trait Implementations

impl Clone for Constant

fn clone(&self) -> Constant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Constant

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

Formats the value using the given formatter.

impl<T, U> Foldable<T, U> for Constant

type Mapped = Constant

fn fold<F: Fold<T, TargetU = U> + ?Sized>( self, _folder: &mut F ) -> Result<Self::Mapped, F::Error>

impl From<BigInt> for Constant

fn from(i: BigInt) -> Constant

Converts to this type from the input type.

impl From<String> for Constant

fn from(s: String) -> Constant

Converts to this type from the input type.

impl From<Vec<u8>> for Constant

fn from(b: Vec<u8>) -> Constant

Converts to this type from the input type.

impl From<bool> for Constant

fn from(b: bool) -> Constant

Converts to this type from the input type.

impl PartialEq for Constant

fn eq(&self, other: &Constant) -> 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.
