----------------- -----------------
| Feature | Description | | Feature | Description |
| ------------ | ----------------------------------------------------------------------------------------------------------------------- | | ------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `debug_msgs` | Print debug messages to stdout (using `println!`) related to function registrations and function calls. | | `debug_msgs` | Print debug messages to stdout related to function registrations and calls. |
| `no_stdlib` | Exclude the standard library of utility functions in the build, and only include the minimum necessary functionalities. | | `no_stdlib` | Exclude the standard library of utility functions in the build, and only include the minimum necessary functionalities. Standard types are not affected. |
| `unchecked` | Exclude arithmetic checking in the standard library. Beware that a bad script may panic the entire system! | | `unchecked` | Exclude arithmetic checking (such as overflows and division by zero). Beware that a bad script may panic the entire system! |
| `no_index` | Disable arrays and indexing features if you don't need them. | | `no_index` | Disable arrays and indexing features if you don't need them. |
| `no_float` | Disable floating-point numbers and math if you don't need them. | | `no_float` | Disable floating-point numbers and math if you don't need them. |
| `only_i32` | Set the system integer type to `i32` and disable all other integer types. |
| `only_i64` | Set the system integer type to `i64` and disable all other integer types. |
By default, Rhai includes all the standard functionalities in a small, tight package. Most features are here for you to opt-**out** of certain functionalities that you do not need.
Excluding unneeded functionalities can result in smaller, faster builds as well as less bugs due to a more restricted language.

The following primitive types are supported natively: The following primitive types are supported natively:
| Category | Types | | Category | Types |

| Integer | `i32`, `u32`, `i64` _(default)_, `u64` | | **Integer** | `u8`, `i8`, `u16`, `i16`, <br/>`u32`, `i32` (default for [`only_i32`](#optional-features)),<br/>`u64`, `i64` _(default)_ |

| **System** (current configuration) | `rhai::INT` (`i32` or `i64`),<br/>`rhai::FLOAT` (`f32` or `f64`) |
All types are treated strictly separate by Rhai, meaning that `i32` and `i64` and `u32` are completely different; you cannot even add them together.
The default integer type is `i64`. If you do not need any other integer type, you can enable the [`only_i64`](#optional-features) feature.
If you only need 32-bit integers, you can enable the [`only_i32`](#optional-features) feature and remove support for all integer types other than `i32` including `i64`.
This is useful on 32-bit systems where using 64-bit integers incurs a performance penalty.
If you do not need floating-point, enable the [`no_float`](#optional-features) feature to remove support.
Value conversions Value conversions
----------------- -----------------
All types are treated strictly separate by Rhai, meaning that `i32` and `i64` and `u32` are completely different; you cannot even add them together.
There is a `to_float` function to convert a supported number to an `f64`, and a `to_int` function to convert a supported number to `i64` and that's about it. For other conversions you can register your own conversion functions. There is a `to_float` function to convert a supported number to an `f64`, and a `to_int` function to convert a supported number to `i64` and that's about it. For other conversions you can register your own conversion functions.
There is also a `type_of` function to detect the type of a value. There is also a `type_of` function to detect the type of a value.
