Struct x509_cert::ext::Extension

pub struct Extension {
    pub extn_id: ObjectIdentifier,
    pub critical: bool,
    pub extn_value: OctetString,
}

Extension as defined in RFC 5280 Section 4.1.2.9.

The ASN.1 definition for Extension objects is below. The extnValue type may be further parsed using a decoder corresponding to the extnID value.

Extension  ::=  SEQUENCE  {
    extnID      OBJECT IDENTIFIER,
    critical    BOOLEAN DEFAULT FALSE,
    extnValue   OCTET STRING
                -- contains the DER encoding of an ASN.1 value
                -- corresponding to the extension type identified
                -- by extnID
}

Fields

extn_id: ObjectIdentifier

critical: bool

extn_value: OctetString

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Extension

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for Extension

fn clone(&self) -> Extension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Extension

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

Formats the value using the given formatter.

impl<'__der_lifetime> DecodeValue<'__der_lifetime> for Extension

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 Extension

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 Extension

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ValueOrd for Extension

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 Extension

impl<'__der_lifetime> Sequence<'__der_lifetime> for Extension

impl StructuralEq for Extension

impl StructuralPartialEq for Extension
