//! oid crate by <https://github.com/UnnecessaryEngineering/oid> turned into vendore'd module
//!
//! [Object Identifiers] are a standard of the [ITU] used to reference objects, things, and
//! concepts in a globally unique way. This crate provides for data structures and methods
//! to build, parse, and format OIDs.
//!

//! ## Parsing OID String Representation

//!
//! fn main() -> Result<(), ObjectIdentifierError> {
//! let oid = ObjectIdentifier::try_from("0.1.2.3")?;
//! Ok(())
//! }

//!
//! ## Parsing OID Binary Representation
2021-10-18 10:39:31 +02:00
//! ```ignore
