[−][src]Function cjdns_core::splice::re_encode
pub fn re_encode<L: LabelBits>(
label: RoutingLabel<L>,
scheme: &EncodingScheme,
desired_form_num: Option<u8>
) -> Result<RoutingLabel<L>>
Re-encode a label to the encoding form specified by desired_form_num
(or canonical if None).
This will re-encode a label to the encoding form specified by desired_form_num.
This may return an error if the encoding form cannot
be detected, you pass an invalid desired_form_num or if you try to re-encode the self route
(0001). It will also return an error if re-encoding a label will make it too long (more than Label::max_bit_size()
bits). If desired_form_num is None then it will re-encode the label
into it's cannonical form, that is the smallest form which can hold that director.
