Compile a Script (to AST)
|

|

========================

To repeatedly evaluate a script, _compile_ it first into an AST (abstract syntax tree) form:
|
||
|
|
|
||
|
|
```rust
|
||
|
|
// Compile to an AST and store it for later evaluations
|
||
|
|
let ast = engine.compile("40 + 2")?;
|
||
|
|
|
||
|
|
for _ in 0..42 {
|
||
|
|
let result: i64 = engine.eval_ast(&ast)?;
|
||
|
|
|
||
|
|
println!("Answer #{}: {}", i, result); // prints 42
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Compiling a script file is also supported (not available under [`no_std`] or in [WASM] builds):
|
||
|
|
|
||
|
|
```rust
|
||
|
|
let ast = engine.compile_file("hello_world.rhai".into())?;
|
||
|
|
```
