# BrainRustFucked
YABI (Yet Another Brainfuck Interpretator)  
This is designed to embed BrainFuck for applications.

This library provides 2 functions:

```rs

/**
 * Eval the code from a raw string returning the memory
 */
fn eval(bf_str: &&str) -> Result<[u8; 30000], String>

/**
 * A more low level function to run code in custom environment  
 * This is useful when you want to use presetted memory & pointer
 */
fn eval_mem(bf_str: &&str, mem: &mut [u8], pointer: &mut usize) -> Result<(), String>
```

Example code:
```rs
// print "Hello world!"
eval(&"++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.").unwrap();
```
