WebZig solves these problems by 1) eliminating implicit conversions unless they are guaranteed to be safe (for example, assigning a u8 value to a u16 variable cannot fail or lose data) and 2) giving each casting operator its own built-in function, making it easy to audit their use with simple text-based tools. WebAug 23, 2024 · Since you’re working to an external specification, you probably want to mark those structs #[repr(C)] so that they have a stable layout. Assuming there are no endianness issues, you should be able to mem::transmute between a properly-aligned &[u8; SIZE] and a reference to your struct.. Looking at the zerocopy docs, it should mostly work except for … WebThis custom serialize_deserialize_u8_i32 library will safely convert back and forth between u8 array and i32 array i.e. the serialise function will take all of your u8 values and pack them into i32 values and the deserialise function will take this library’s custom i32 values and convert them back to the original u8 values that you started with. mentally strong psychiatry
