Trait AsBytes 

pub trait AsBytes {
    // Required methods
    fn as_bytes(&self) -> &[u8] ;
    fn len(&self) -> usize;

    // Provided methods
    fn to_bytes_vec(&self) -> Vec<u8>  { ... }
    fn byte_size(&self) -> usize { ... }
}

Trait for borrowing data as byte slices. This trait abstracts the conversion of types that implement Pod (or collections thereof) into their raw byte representation as a slice (&[u8]).

Required Methods

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

Returns the underlying byte slice of the data.

fn len(&self) -> usize

Returns the count of elements contained in the data. For single-element tuples (T,), this is 1. For collections (Vec<T>, &[T], [T; N]), this is the number of T items.

Provided Methods

fn to_bytes_vec(&self) -> Vec<u8>

Returns an owned vector containing a copy of the bytes of the data. The default implementation clones the bytes from as_bytes().

fn byte_size(&self) -> usize

Returns the size in bytes of the data.
