Struct 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
