Implementations

Source§

impl ObjectIdentifier

Source

pub const MAX_SIZE: usize = 39usize

Maximum size of a BER/DER-encoded OID in bytes.

Source

pub const fn new_unwrap(s: &str) -> ObjectIdentifier

Parse an ObjectIdentifier from the dot-delimited string form, panicking on parse errors.

This function exists as a workaround for unwrap not yet being stable in const fn contexts, and is intended to allow the result to be bound to a constant value:

use const_oid::ObjectIdentifier;

pub const MY_OID: ObjectIdentifier = ObjectIdentifier::new_unwrap("1.2.840.113549.1.1.1");

In future versions of Rust it should be possible to replace this with ObjectIdentifier::new(...).unwrap().

Use ObjectIdentifier::new for fallible parsing.

Source

pub const fn new(s: &str) -> Result<ObjectIdentifier, Error>

Parse an ObjectIdentifier from the dot-delimited string form.

Source

pub fn from_arcs( arcs: impl IntoIterator<Item = u32>, ) -> Result<ObjectIdentifier, Error>

Parse an OID from a slice of Arc values (i.e. integers).

Source

pub fn from_bytes(ber_bytes: &[u8]) -> Result<ObjectIdentifier, Error>

Parse an OID from from its BER/DER encoding.

Source

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

Get the BER/DER serialization of this OID as bytes.

Note that this encoding omits the tag/length, and only contains the value portion of the encoded OID.

Source

pub fn arc(&self, index: usize) -> Option<u32>

Return the arc with the given index, if it exists.

Source

pub fn arcs(&self) -> Arcs<'_>

Iterate over the arcs (a.k.a. nodes) of an ObjectIdentifier.

Returns Arcs, an iterator over Arc values.

Source

pub fn len(&self) -> usize

Get the length of this ObjectIdentifier in arcs.

Source

pub fn parent(&self) -> Option<ObjectIdentifier>

Get the parent OID of this one (if applicable).

Source

pub const fn push_arc(self, arc: u32) -> Result<ObjectIdentifier, Error>

Push an additional arc onto this OID, returning the child OID.
