Implementations

impl Expression

pub fn evaluate( &self, values: &HashMap<u32, Term>, symbols: &mut TemporarySymbolTable<'_> ) -> Result<Term, Expression>

pub fn print(&self, symbols: &SymbolTable) -> Option<String>

Trait Implementations

impl AsRef<Expression> for Expression

fn as_ref(&self) -> &Expression

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Convert<Expression> for Expression

fn convert(&self, symbols: &mut SymbolTable) -> Expression

fn convert_from(e: &Expression, symbols: &SymbolTable) -> Result<Self, Format>

fn translate( f: &T, from_symbols: &SymbolTable, to_symbols: &mut SymbolTable ) -> Result<T, Format>

impl Debug for Expression

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

Formats the value using the given formatter.

impl Hash for Expression

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 PartialEq<Expression> for Expression

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

impl Eq for Expression

impl StructuralEq for Expression

impl StructuralPartialEq for Expression
