Struct bcder::encode::Nothing

pub struct Nothing;

A encoder for nothing.

Unsurprisingly, this encodes as zero octets of content. It can be useful for writing an encoder for an enum where some of the variants shouldn’t result in content at all.

Trait Implementations

impl Values for Nothing

fn encoded_len(&self, _mode: Mode) -> usize

Returns the length of the encoded values for the given mode.

fn write_encoded<W: Write>(
    &self,
    _mode: Mode,
    _target: &mut W
) -> Result<(), Error>

Encodes the values in the given mode and writes them to target.

fn explicit(self, tag: Tag) -> Constructed<Self>where
    Self: Sized,

Converts the encoder into one with an explicit tag.

fn to_captured(&self, mode: Mode) -> Captured

Captures the encoded values in the given mode.
