gstring - Rust macros to make strings on stack

	/// A helper to build a string on the stack.
	///
	/// Given an array it makes a writeable cursor available to the passed code block.
	///
	/// Returns a &str slice pointing at memory between the array start and the cursor.
	///
	/// Example:
	///
	/// use std::io::Write;
	/// let mut foobar: [u8; 128] = unsafe {std::mem::uninitialized()};
