Use Engine::new(). 2020-10-07 15:52:24 +08:00			`use rhai::{Engine, EvalAltResult, INT};`
Fix type register visibility. Add a few more examples 2016-03-03 11:08:34 -05:00
Make all public API's return Box<EvalAltResult> to reduce footprint. 2020-04-21 23:25:12 +08:00			`fn main() -> Result<(), Box<EvalAltResult>> {`
Use Engine::new(). 2020-10-07 15:52:24 +08:00			`let engine = Engine::new();`
Fix type register visibility. Add a few more examples 2016-03-03 11:08:34 -05:00
Refine examples. 2021-02-20 23:46:25 +08:00			`engine.consume(r#"print("hello, world!")"#)?;`

Use INT in examples instead of i64. 2020-03-24 09:49:08 +08:00			`let result = engine.eval::<INT>("40 + 2")?;`
Use ? operator for examples. 2020-03-09 16:54:43 +08:00
			`println!("Answer: {}", result); // prints 42`

			`Ok(())`
