Trait ssb_keyfile::AsBytes

pub unsafe trait AsBytes {
    fn as_bytes(&self) -> &[u8] { ... }
    fn as_bytes_mut(&mut self) -> &mut [u8]
    where
        Self: FromBytes,
    { ... }
}

Types which are safe to treat as an immutable byte slice.

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

AsBytes types can be safely viewed as a slice of bytes. In particular, this means that, in any valid instance of the type, none of the bytes of the instance are uninitialized. This precludes the following types:

• Structs with internal padding
• Unions in which not all variants have the same length

AsBytes is ignorant of byte order. For byte order-aware types, see the [byteorder] module.

Custom Derive Errors

Due to the way that the custom derive for AsBytes is implemented, you may get an error like this:

error[E0080]: evaluation of constant value failed
  --> lib.rs:1:10
   |
 1 | #[derive(AsBytes)]
   |          ^^^^^^^ attempt to divide by zero

This error means that the type being annotated has padding bytes, which is illegal for AsBytes types. Consider either adding explicit struct fields where those padding bytes would be or using #[repr(packed)].

Safety

If T: AsBytes, then unsafe code may assume that it is sound to treat any instance of the type as an immutable [u8] of length size_of::<T>(). If a type is marked as AsBytes which violates this contract, it may cause undefined behavior.

If a type has the following properties, then it is safe to implement AsBytes 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 be AsBytes
  • Its layout must have no padding. This is always true for repr(transparent) and repr(packed). For repr(C), see the layout algorithm described in the Rust Reference.
• 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).

Provided methods

fn as_bytes(&self) -> &[u8]

Get the bytes of this value.

as_bytes provides access to the bytes of this value as an immutable byte slice.

fn as_bytes_mut(&mut self) -> &mut [u8] where
    Self: FromBytes, 

Get the bytes of this value mutably.

as_bytes_mut provides access to the bytes of this value as a mutable byte slice.
