//! eagre-asn1
//! ==========
//!
//! eagre-asn1 is an asn1 library for [Rust](https://www.rust-lang.org/).
//!
//! It makes heavy use of macros to make the interface easy to use.
//!
//! Currently only DER and a very small bit of XER is supported.
//!
//! ## Example ##
//! Say you have the following asn1 structure:
//!
//! ```text
//! User ::= SEQUENCE {
//!     username         UTF8String,
//!     passwordHash     [CONTEXT 12] IMPLICIT OctetString,
//!     age              [APPLICATION 1] EXPLICIT Integer,
//!     admin            Boolean
//! }
//! ```
//!
//! In Rust it would look like this:
//!
//! ```ignore
//! struct User {
//!     pub username: String,
//!     pub password_hash: Vec<u8>,
//!     pub age: i32,
//!     pub admin: bool,
//! }
//!
//! der_sequence!{
//!     User:
//!         username:      NOTAG                       TYPE String,
//!         password_hash: IMPLICIT TAG CONTEXT 12;    TYPE Vec<u8>,
//!         age:           EXPLICIT TAG APPLICATION 1; TYPE i32,
//!         admin:         NOTAG                       TYPE bool,
//! }
//! ```
//!
//! And serializing is as easy as:
//!
//! ```ignore
//! use eagre_asn1::der::DER;
//!
//! let some_user = User { ... };
//! let encoded = some_user.der_bytes().unwrap();
//! Send to far away planet
//! let decoded = User::der_from_bytes(encoded).unwrap();
//! assert_eq!(some_user, decoded);
//! ```
//!
