Address Rust String Null Byte Handling

[arriqaaq]

Description:

Rust strings can freely contain null bytes. For example, "foo\0bar" is allowed in Rust and has a length of 7. Adding a null byte in Rust might result in a prefixed string.

As an alternative, consider using something like 0b10111111. All Rust strings are valid UTF-8, and a UTF-8 character can never begin with a 10-bit pattern, as this is the starting pattern of a continuation byte. Utilizing 0b10111111 in Rust strings would ensure that no byte slice derived from a string serves as a prefix for another.

Action Items:

• Evaluate the possibility of using 0b10111111 as an alternative to null bytes.

Additional Context:

This consideration aims to prevent unintended string prefixing when adding bytes in Rust. This was raised by @DelSkayn here
