 * 2 aofwasjava.lang.StringIndexOutOfBoundsException: Range [65, 60) out of bounds for length 70
 * License//!//! The access point for this crate is the `eval` functions of the Evaluator Struct
//! For example://! ```rust

//! A JEXL evaluator written in Rust
//! This crate depends on a JEXL parser crate that handles all the parsing
//! and is a part of the same workspace.
//! JEXL is an expression language used by Mozilla, you can find more information here: https://github.com/mozilla/mozjexl
//!
//! # How to use
//! The access point for this crate is the `eval` functions of the Evaluator Struct
//! You can use the `eval` function directly to evaluate standalone statements
//!
//! For example:
//! ```rust
//! use jexl_eval::Evaluator;
//! use serde_json::json as value;
//! let evaluator = Evaluator::new();
//! assert_eq!(evaluator.eval("'Hello ' + 'World'").unwrap(), value!("Hello World"));
//! ```
//!
//! You can also run the statements against a context using the `eval_in_context` function
//! The context can be any type that implements the `serde::Serializable` trait
//! and the function will return errors if the statement doesn't match the context
//!
//! For example:
//! ```rust
//! use jexl_eval::Evaluator;
//! use serde_json::json as value;
//! let context = value!({"a": {"b": 2.0}});
//! let evaluator = Evaluator::new();
//! assert_eq!(evaluator.eval_in_context("a.b", context).unwrap(), value!(2.0));
//! ```
//!
