Implementations

impl Expression

pub fn simplify(&self, variables: &mut HashMap<String, Expression>) -> Self

Simplify this expression, given a reference to a list of variables.

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl Display for Expression

Implementing std::fmt::Display allows us to print expressions using the default formatter.

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

Display each Expression.
