    Summary: Unsound casting in flatbuffers

    Details: The implementation of impl Follow for bool allows to reinterpret arbitrary bytes as a bool. In Rust bool has stringent requirements for its in-memory representation. Use of this function allows to violate these requirements and invoke undefined behaviour in safe code.
