pub fn parse_expression(source: &str) -> Result<Expression, ParseError>

Parses a python expression

Example

extern crate num_bigint;
use num_bigint::BigInt;
use rustpython_parser::{parser, ast};
let expr = parser::parse_expression("1+2").unwrap();

assert_eq!(ast::Expression::Binop {
        a: Box::new(ast::Expression::Number {
            value: ast::Number::Integer { value: BigInt::from(1) }
        }),
        op: ast::Operator::Add,
        b: Box::new(ast::Expression::Number {
            value: ast::Number::Integer { value: BigInt::from(2) }
        })
    },
    expr);
