Sealed trait implemented by all physical types that can be allocated, serialized and deserialized by this crate. All O(N) allocations in this crate are done for this trait alone.

Required Associated Types

type Bytes: AsRef<[u8]> + AsMut<[u8]> + Index<usize, Output = u8> + IndexMut<usize, Output = u8> + for<'a> TryFrom<&'a [u8]> + Debug + Default + IntoIterator<Item = u8>

Type denoting its representation as bytes. This is [u8; N] where N = size_of::<T>.

Required Associated Constants

const PRIMITIVE: PrimitiveType

The corresponding variant of PrimitiveType.

Required Methods

fn to_le_bytes(&self) -> Self::Bytes

To bytes in little endian

fn to_be_bytes(&self) -> Self::Bytes

To bytes in big endian

fn from_le_bytes(bytes: Self::Bytes) -> Self

From bytes in little endian

fn from_be_bytes(bytes: Self::Bytes) -> Self

From bytes in big endian

Object Safety

This trait is not object safe.
