Struct FunctionBuilder

pub struct FunctionBuilder { /* private fields */ }

A constructor of a function. Consider using the [crate::fun!] macro instead.

For example:

let f_id = symbol!("f"; Symmetric);
let fb = FunctionBuilder::new(f_id);
let a = fb
    .add_arg(&Atom::num(3))
    .add_arg(&Atom::num(2))
    .add_arg(&Atom::num(1))
    .finish();

println!("{}", a);
