Struct Oid 

pub struct Oid<'a> { /* private fields */ }

Available on crate feature mtls only.

Object ID (OID) representation which can be relative or non-relative. An example for an OID in string representation is "1.2.840.113549.1.1.5".

For non-relative OIDs restrictions apply to the first two components.

This library contains a procedural macro oid which can be used to create oids. For example oid!(1.2.44.233) or oid!(rel 44.233) for relative oids. See the module documentation for more information.

Implementations

impl<'a> Oid<'a>

pub const fn new(asn1: Cow<'a, [u8]>) -> Oid<'a>

Create an OID from the ASN.1 DER encoded form. See the module documentation for other ways to create oids.

pub const fn new_relative(asn1: Cow<'a, [u8]>) -> Oid<'a>

Create a relative OID from the ASN.1 DER encoded form. See the module documentation for other ways to create relative oids.

pub fn from(s: &[u64]) -> Result<Oid<'static>, OidParseError>

Build an OID from an array of object identifier components. This method allocates memory on the heap.

pub fn from_relative(s: &[u64]) -> Result<Oid<'static>, OidParseError>

Build a relative OID from an array of object identifier components.

pub fn to_owned(&self) -> Oid<'static>

Create a deep copy of the oid.

This method allocates data on the heap. The returned oid can be used without keeping the ASN.1 representation around.

Cloning the returned oid does again allocate data.

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

Get the encoded oid without the header.

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

👎Deprecated since 0.2.0: Use as_bytes instead

Get the encoded oid without the header.

pub fn into_cow(self) -> Cow<'a, [u8]>

Get the bytes representation of the encoded oid

pub fn to_id_string(&self) -> String

Convert the OID to a string representation.

If every arc fits into a u64 a string like “1.2.840.113549.1.1.5” is returned, otherwise a hex representation.

See also the “bigint” feature of this crate.

pub fn iter(&self) -> Option<impl FusedIterator + ExactSizeIterator>

Return an iterator over the sub-identifiers (arcs). Returns None if at least one arc does not fit into u64.

pub fn from_ber_relative( bytes: &'a [u8], ) -> Result<(&'a [u8], Oid<'a>), Err<Error>>

pub fn from_der_relative( bytes: &'a [u8], ) -> Result<(&'a [u8], Oid<'a>), Err<Error>>

pub fn starts_with(&self, needle: &Oid<'_>) -> bool

Returns true if needle is a prefix of the OID.

Trait Implementations

impl<'a> CheckDerConstraints for Oid<'a>

fn check_constraints(any: &Any<'_>) -> Result<(), Error>

impl<'a> Clone for Oid<'a>

fn clone(&self) -> Oid<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Oid<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Oid<'a>

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

Formats the value using the given formatter.

impl<'a> From<Oid<'a>> for BerObject<'a>

Build a DER object from an OID.

fn from(oid: Oid<'a>) -> BerObject<'a>

Converts to this type from the input type.

impl<'a> FromStr for Oid<'a>

type Err = OidParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Oid<'a>, <Oid<'a> as FromStr>::Err>

Parses a string s to return a value of this type.

impl<'a> Hash for Oid<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for Oid<'a>

fn eq(&self, other: &Oid<'a>) -> 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.

impl<'a> Tagged for Oid<'a>

const TAG: Tag = Tag::Oid

impl ToDer for Oid<'_>

fn to_der_len(&self) -> Result<usize, Error>

Get the length of the object (including the header), when encoded

fn write_der_header( &self, writer: &mut dyn Write, ) -> Result<usize, SerializeError>

Attempt to write the DER header to this writer.

fn write_der_content( &self, writer: &mut dyn Write, ) -> Result<usize, SerializeError>

Attempt to write the DER content (all except header) to this writer.

fn to_der_vec(&self) -> Result<Vec<u8>, SerializeError>

Write the DER encoded representation to a newly allocated Vec<u8>.

fn to_der_vec_raw(&self) -> Result<Vec<u8>, SerializeError>

Similar to using to_vec, but uses provided values without changes. This can generate an invalid encoding for a DER object.

fn write_der(&self, writer: &mut dyn Write) -> Result<usize, SerializeError>

Attempt to write the DER encoded representation (header and content) into this writer.

fn write_der_raw(&self, writer: &mut dyn Write) -> Result<usize, SerializeError>

Similar to using to_der, but uses provided values without changes. This can generate an invalid encoding for a DER object.

impl<'a, 'b> TryFrom<&'b Any<'a>> for Oid<'a>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: &'b Any<'a>) -> Result<Oid<'a>, Error>

Performs the conversion.

impl<'a> TryFrom<Any<'a>> for Oid<'a>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(any: Any<'a>) -> Result<Oid<'a>, Error>

Performs the conversion.
