-/// A ZeroCopyBuf encapsulates a slice that's been borrowed from a JavaScript
-/// ArrayBuffer object. JavaScript objects can normally be garbage collected,
-/// but the existence of a ZeroCopyBuf inhibits this until it is dropped. It
-/// behaves much like an Arc<[u8]>.
-///
-/// # Cloning
-/// Cloning a ZeroCopyBuf does not clone the contents of the buffer,
-/// it creates a new reference to that buffer.
-///
-/// To actually clone the contents of the buffer do
-/// `let copy = Vec::from(&*zero_copy_buf);`
