Enum mexprp::Term

pub enum Term<N: Num> {
    Num(Answer<N>),
    Operation(Rc<Operate<N>>),
    Function(String, Vec<Term<N>>),
    Var(String),
}

The main representation of parsed equations. It is an operand that can contain an operation between more of itself. This form is the only one that can be directly evaluated. Does not include it's own context.

Variants

Num(Answer<N>)

A number

Operation(Rc<Operate<N>>)

An operation

Function(String, Vec<Term<N>>)

A function with the given arguments

Var(String)

A variable
