Implementations

impl Expr

pub fn invert( &self, symbol_table: &mut SymbolTable, unknown_var: &str ) -> Result<Self, KalkError>

pub fn invert_to_target( &self, symbol_table: &mut SymbolTable, target_expr: Expr, unknown_var: &str ) -> Result<Self, KalkError>

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl PartialEq for Expr

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