Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl From<Value> for TestHelper<Term>

fn from(other: Value) -> Self

Performs the conversion.

impl From<Value> for TestHelper<Parameter>

fn from(name: Value) -> Self

Convert a Value to a parameter. If the value is a symbol, it is used as the parameter name. Otherwise it is assumed to be a specializer.

impl Hash for Value

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Value> for Value

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

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

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

This method tests for !=.

impl Serialize for Value

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl ToPolarString for Value

fn to_polar(&self) -> String

impl Eq for Value

impl StructuralEq for Value

impl StructuralPartialEq for Value
