[−][src]Trait zerocopy::FromBytes

pub unsafe trait FromBytes { }

Types for which any byte pattern is valid.

WARNING: Do not implement this trait yourself! Instead, use #[derive(FromBytes)].

FromBytes types can safely be deserialized from an untrusted sequence of bytes because any byte sequence corresponds to a valid instance of the type.

Safety

If T: FromBytes, then unsafe code may assume that it is sound to treat any initialized sequence of bytes of length size_of::<T>() as a T. If a type is marked as FromBytes which violates this contract, it may cause undefined behavior.

If a type has the following properties, then it is safe to implement FromBytes for that type:

If the type is a struct:
- It must have a defined representation (repr(C), repr(transparent), or repr(packed))
- All of its fields must implement FromBytes
If the type is an enum:
- It must be a C-like enum (meaning that all variants have no fields)
- It must have a defined representation (reprs C, u8, u16, u32, u64, usize, i8, i16, i32, i64, or isize).
- The maximum number of discriminants must be used (so that every possible bit pattern is a valid one). Be very careful when using the C, usize, or isize representations, as their size is platform-dependent.
