Struct rocket::mtls::oid::asn1_rs::Oid

source ·
pub struct Oid<'a> { /* private fields */ }
Available on crate feature mtls only.
Expand description

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§

source§

impl<'a> Oid<'a>

source

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.

source

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.

source

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

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

source

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

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

source

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.

source

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

Get the encoded oid without the header.

source

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

👎Deprecated since 0.2.0: Use as_bytes instead

Get the encoded oid without the header.

source

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

Get the bytes representation of the encoded oid

source

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.

source

pub fn iter( &self ) -> Option<impl Iterator<Item = u64> + FusedIterator + ExactSizeIterator>

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

source

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

source

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

fn quirk(&self, value: Quirk) -> Painted<&T>
