The String API in iceoryx2-bb-container exposes its contents as mutable bytes through safe APIs, while String::as_str() converts those bytes into a Rust string slice without validating UTF-8. An application can therefore create an invalid &str and trigger undefined behavior using entirely safe Rust.
The API methods as_mut_bytes and deref_mut where removed from the String API and their implementations (PolymorphicString, RelocatableString, and StaticString ) without replacement.
