Maximum Number of Functions
|
|
===========================
|
|
|
|
{{#include ../links.md}}
|
|
|
|
Rhai by default does not limit how many [functions] can be defined in a script.
|
|
|
|
This can be changed via the [`Engine::set_max_functions`][options] method. Notice that setting the
|
|
maximum number of [functions] to zero does _not_ indicate unlimited [functions], but disallows
|
|
defining any scripted [function] altogether.
|
|
|
|
A script attempting to load more than the maximum number of [functions] will terminate with a parse error.
|
|
|
|
This check can be disabled via the [`unchecked`] feature for higher performance (but higher risks as well).
|
|
|
|
```rust
|
|
let mut engine = Engine::new();
|
|
|
|
engine.set_max_functions(5); // allow defining only up to 5 functions
|
|
|
|
engine.set_max_functions(0); // disallow defining function (maximum = zero)
|
|
|
|
engine.set_max_functions(1000); // set to a large number for effectively unlimited functions
|
|
```
