impl<Params> EncodeValue for RsaOaepParams<Params>

where AlgorithmIdentifier<Params>: AsAlgorithmIdentifierRef + From<AlgorithmIdentifierRef<'static>>, for<'b> Option<ContextSpecificRef<'b, AlgorithmIdentifier<Params>>>: Encode, for<'b> Option<ContextSpecificRef<'b, AlgorithmIdentifier<AlgorithmIdentifier<Params>>>>: Encode, Params: PartialEq,

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

Compute the length of this value (sans [Tag]+Length header) when encoded as ASN.1 DER.

fn encode_value(&self, writer: &mut impl Writer) -> Result<()>

Encode value (sans [Tag]+Length header) as ASN.1 DER using the provided Writer.
