Struct Asn1Object 

pub struct Asn1Object(/* private fields */);

Object Identifier

Represents an ASN.1 Object. Typically, NIDs, or numeric identifiers are stored as a table within the Nid module. These constants are used to determine attributes of a certificate, such as mapping the attribute “CommonName” to “CN” which is represented as the OID of 13. This attribute is a constant in the nid::COMMONNAME.

Implementations

impl Asn1Object

pub fn from_str(txt: &str) -> Result<Asn1Object, ErrorStack>

Constructs an ASN.1 Object Identifier from a string representation of the OID.

This corresponds to OBJ_txt2obj.

pub fn as_slice(&self) -> &[u8]

Return the OID as an DER encoded array of bytes. This is the ASN.1 value, not including tag or length.

Requires OpenSSL 1.1.1 or newer.

This corresponds to OBJ_get0_data.

Methods from Deref<Target = Asn1ObjectRef>

pub fn nid(&self) -> Nid

Returns the NID associated with this OID.

Trait Implementations

impl AsRef<Asn1ObjectRef> for Asn1Object

fn as_ref(&self) -> &Asn1ObjectRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<Asn1ObjectRef> for Asn1Object

fn borrow(&self) -> &Asn1ObjectRef

Immutably borrows from an owned value.

impl Clone for Asn1Object

fn clone(&self) -> Asn1Object

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Deref for Asn1Object

type Target = Asn1ObjectRef

The resulting type after dereferencing.

fn deref(&self) -> &Asn1ObjectRef

Dereferences the value.

impl DerefMut for Asn1Object

fn deref_mut(&mut self) -> &mut Asn1ObjectRef

Mutably dereferences the value.

impl Drop for Asn1Object

fn drop(&mut self)

Executes the destructor for this type.

impl ForeignType for Asn1Object

type CType = ASN1_OBJECT

The raw C type.

type Ref = Asn1ObjectRef

The type representing a reference to this type.

unsafe fn from_ptr(ptr: *mut ASN1_OBJECT) -> Asn1Object

Constructs an instance of this type from its raw type.

fn as_ptr(&self) -> *mut ASN1_OBJECT

Returns a raw pointer to the wrapped value.

impl Stackable for Asn1Object

type StackType = stack_st_ASN1_OBJECT

The C stack type for this element.

impl Send for Asn1Object

impl Sync for Asn1Object

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
