Enum EcParameters 

pub enum EcParameters {
    NamedCurve(ObjectIdentifier),
}

Elliptic curve parameters as described in RFC5480 Section 2.1.1:

ECParameters ::= CHOICE {
  namedCurve         OBJECT IDENTIFIER
  -- implicitCurve   NULL
  -- specifiedCurve  SpecifiedECDomain
}
  -- implicitCurve and specifiedCurve MUST NOT be used in PKIX.
  -- Details for SpecifiedECDomain can be found in [X9.62].
  -- Any future additions to this CHOICE should be coordinated
  -- with ANSI X9.

Variants

NamedCurve(ObjectIdentifier)

Elliptic curve named by a particular OID.

namedCurve identifies all the required values for a particular set of elliptic curve domain parameters to be represented by an object identifier.

Implementations

impl EcParameters

pub fn named_curve(self) -> Option<ObjectIdentifier>

Obtain the namedCurve OID.

Trait Implementations

impl Clone for EcParameters

fn clone(&self) -> EcParameters

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EcParameters

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

Formats the value using the given formatter.

impl<'a> DecodeValue<'a> for EcParameters

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

Attempt to decode this message using the provided Reader.

impl EncodeValue for EcParameters

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 FixedTag for EcParameters

const TAG: Tag = Tag::ObjectIdentifier

ASN.1 tag

impl<'a> From<&'a EcParameters> for AnyRef<'a>

fn from(params: &'a EcParameters) -> AnyRef<'a>

Converts to this type from the input type.

impl From<ObjectIdentifier> for EcParameters

fn from(oid: ObjectIdentifier) -> EcParameters

Converts to this type from the input type.

impl PartialEq for EcParameters

fn eq(&self, other: &EcParameters) -> 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.
