Struct Oid 

pub struct Oid { /* private fields */ }

An owned Object Identifier wrapping an OpenSSL ASN1_OBJECT*.

Oid::from_text accepts any dotted decimal OID string ("1.3.6.1.5.2.3.5") or registered short name ("sha256"), returning an Oid even for OIDs that are not in OpenSSL’s built-in NID table. For registered OIDs, Oid::nid returns the corresponding NID; for unregistered OIDs it returns 0 (NID_undef).

Two Oid values compare equal when their ASN.1 encodings are identical, regardless of whether either has a registered NID.

Implementations

impl Oid

pub fn from_text(s: &str) -> Result<Self, ErrorStack>

Construct from a dotted decimal OID string ("1.3.6.1.5.2.3.5") or a registered short name ("sha256").

Unlike crate::x509::nid_from_text, this succeeds for OIDs that are not registered in OpenSSL’s built-in NID table.

Errors

Returns an ErrorStack if s is not a valid OID string or name, or if s contains an interior NUL byte.

pub fn nid(&self) -> i32

Return the NID for this OID, or 0 (NID_undef) if the OID is not registered in OpenSSL’s built-in NID table.

Trait Implementations

impl Clone for Oid

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Oid

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

Formats the value using the given formatter.

impl Display for Oid

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

Formats the value using the given formatter.

impl Drop for Oid

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for Oid

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