Malformed bencode input, unmarshaler failed to parse it.

A non-nil error was returned after calling UnmarshalBencode on a type which implements the Unmarshaler interface.

Unmarshaler tried to write to an unexported (therefore unwritable) field.

Unmarshal argument must be a non-nil value of some pointer type.

Unmarshaler spotted a value that was not appropriate for a given Go value.

Any type which implements this interface, will be marshaled using the specified method.
