     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

id: Oid

critical: Option<bool>

Implementations

impl Extension

pub fn take_opt_from<S: Source>(
    cons: &mut Constructed<'_, S>
) -> Result<Option<Self>, DecodeError<S::Error>>

Examples found in repository

src/rfc5280.rs (line 486)

    pub fn from_sequence<S: Source>(
        cons: &mut Constructed<S>,
    ) -> Result<Self, DecodeError<S::Error>> {
        let mut extensions = Vec::new();

        while let Some(extension) = Extension::take_opt_from(cons)? {
            extensions.push(extension);
        }

        Ok(Self(extensions))
    }

pub fn take_from<S: Source>(
    cons: &mut Constructed<'_, S>
) -> Result<Self, DecodeError<S::Error>>

pub fn encode_ref(&self) -> impl Values + '_

Examples found in repository

src/rfc5280.rs (line 596)

    fn encoded_len(&self, mode: Mode) -> usize {
        self.encode_ref().encoded_len(mode)
    }

    fn write_encoded<W: Write>(&self, mode: Mode, target: &mut W) -> Result<(), std::io::Error> {
        self.encode_ref().write_encoded(mode, target)
    }

pub fn try_decode_sequence_single_oid(&self) -> Option<Oid>

Attempt to decode a single OID present in an outer sequence.

If this works, we return Some. Else None.

Trait Implementations

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 PartialEq<Extension> 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 Values for Extension

fn encoded_len(&self, mode: Mode) -> usize

Returns the length of the encoded values for the given mode.

fn write_encoded<W: Write>(&self, mode: Mode, target: &mut W) -> Result<(), Error>

Encodes the values in the given mode and writes them to target.

fn explicit(self, tag: Tag) -> Constructed<Self>where
    Self: Sized,

Converts the encoder into one with an explicit tag.

fn to_captured(&self, mode: Mode) -> Captured

Captures the encoded values in the given mode.
