Struct Null 

pub struct Null;

ASN.1 NULL — the type with exactly one value and no content.

Encoded as the two-byte sequence 0x05 0x00 (tag 5, length 0). Commonly used as the parameters field in AlgorithmIdentifier when the algorithm takes no parameters (e.g. in RSA or many hash algorithm OIDs).

Trait Implementations

impl Clone for Null

fn clone(&self) -> Null

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

impl Decode<'_> for Null

fn decode(decoder: &mut Decoder<'_>) -> Result<Self>

impl Encode for Null

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

Encode this value as ASN.1 TLV bytes into encoder.

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

Return the number of bytes that encode will write.
