    fn forward_read_bytes<V>(

        V: Visitor<'storage>;
}

An optional Read trait for advanced Bincode usage.

It is highly recommended to use bincode with io::Read or &[u8] before implementing a custom BincodeRead.

The forward_read_* methods are necessary because some byte sources want to pass a long-lived borrow to the visitor and others want to pass a transient slice.

Required methods

fn forward_read_str<V>(
    &mut self,
    length: usize,
    visitor: V
) -> Result<<V as Visitor<'storage>>::Value, Box<ErrorKind>> where
    V: Visitor<'storage>, 

Check that the next length bytes are a valid string and pass it on to the serde reader.

fn get_byte_buffer(&mut self, length: usize) -> Result<Vec<u8>, Box<ErrorKind>>

Transfer ownership of the next length bytes to the caller.

fn forward_read_bytes<V>(
    &mut self,
    length: usize,
    visitor: V
) -> Result<<V as Visitor<'storage>>::Value, Box<ErrorKind>> where
    V: Visitor<'storage>, 

Pass a slice of the next length bytes on to the serde reader.
