Trait Implementations

source

impl<'a, T> Encodable for OptionalRef<'a, T> where
T: Encodable,

source

fn encoded_len(&self) -> Result<Length>

Compute the length of this value in bytes when encoded as ASN.1 DER.

source

fn encode(&self, encoder: &mut Encoder<'_>) -> Result<()>

Encode this value as ASN.1 DER using the provided Encoder.

source

fn encode_to_slice<'a>(&self, buf: &'a mut [u8]) -> Result<&'a [u8]>
