Efficient and ergonomic representation of Wolfram expressions in Rust.

Examples

Construct the expression {1, 2, 3}:

use wolfram_expr::{Expr, Symbol};

let expr = Expr::normal(Symbol::new("System`List"), vec![
    Expr::from(1),
    Expr::from(2),
    Expr::from(3)
]);

Pattern match over different expression variants:

use wolfram_expr::{Expr, ExprKind};

let expr = Expr::from("some arbitrary expression");

match expr.kind() {
    ExprKind::Integer(1) => println!("got 1"),
    ExprKind::Integer(n) => println!("got {}", n),
    ExprKind::Real(_) => println!("got a real number"),
    ExprKind::String(s) => println!("got string: {}", s),
    ExprKind::Symbol(sym) => println!("got symbol named {}", sym.symbol_name()),
    ExprKind::Normal(e) => println!(
        "got expr with head {} and length {}",
        e.head(),
        e.elements().len()
    ),
}
