Struct Attribute

pub struct Attribute {
    pub oid: AttributeType,
    pub values: SetOfVec<AttributeValue>,
}

X.501 Attribute as defined in RFC 5280 Appendix A.1.

Attribute               ::= SEQUENCE {
    type             AttributeType,
    values    SET OF AttributeValue -- at least one value is required
}

Note that RFC 2986 Section 4 defines a constrained version of this type:

Attribute { ATTRIBUTE:IOSet } ::= SEQUENCE {
    type   ATTRIBUTE.&id({IOSet}),
    values SET SIZE(1..MAX) OF ATTRIBUTE.&Type({IOSet}{@type})
}

The unconstrained version should be preferred.

Fields

oid: AttributeType

values: SetOfVec<AttributeValue>

Trait Implementations

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attribute

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'__der_lifetime> DecodeValue<'__der_lifetime> for Attribute

fn decode_value<R: Reader<'__der_lifetime>>( reader: &mut R, header: Header, ) -> Result<Self>

Attempt to decode this message using the provided Reader.

impl<'__der_lifetime> EncodeValue for Attribute

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.

fn header(&self) -> Result<Header, Error>

where Self: Tagged,

Get the Header used to encode this value.

impl PartialEq for Attribute

fn eq(&self, other: &Attribute) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<ExtensionReq> for Attribute

type Error = Error

The type returned in the event of a conversion error.

fn try_from(extension_req: ExtensionReq) -> Result<Attribute>

Performs the conversion.

impl ValueOrd for Attribute

fn value_cmp(&self, other: &Self) -> Result<Ordering>

Return an Ordering between value portion of TLV-encoded self and other when serialized as ASN.1 DER.

impl Eq for Attribute

impl<'__der_lifetime> Sequence<'__der_lifetime> for Attribute

impl StructuralPartialEq for Attribute
