Brainfuck interpreter in Rust

This repository contains a tiny implementation of the Brainfuck language.

A brainfuck program is written in clear text and only contains eight tokens of relevance. Anything else is silently ignored.

Character	Implemented	Meaning
>	Yes	Increment the data pointer (to point to the next cell to the right).
<	Yes	Decrement the data pointer (to point to the next cell to the left).
+	Yes	Increment (increase by one) the byte at the data pointer.
-	Yes	Decrement (decrease by one) the byte at the data pointer.
.	Yes	Output the byte at the data pointer.
,	No	Accept one byte of input, storing its value in the byte at the data pointer.
[	Yes	If the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.
]	Yes	If the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.
