+//! Basic Encoding Rules (BER) objects and parser
+//!
+//! # BER Objects
+//!
+//! The main object of this crate is [`BerObject`]. It contains a header (ber tag, class, and size)
+//! and content.
+//!
+//! To parse primitive objects (for ex. integers or strings), use the `parse_ber_` set of
+//! functions.
+//!
+//! Constructed objects (like sequences, sets or tagged objects) require to use a combinator. This
+//! combinator takes a function or closure as input, and returns a new, specialized parser.
+//! See the [nom](https://github.com/geal/nom) parser combinator library for more details on
+//! combinators.
+//!
+//! # Examples
+//!
+//! Parse two BER integers:
+//!
+//! ```rust
+//! use der_parser::ber::parse_ber_integer;
+//!
+//! let bytes = [ 0x02, 0x03, 0x01, 0x00, 0x01,
+//!               0x02, 0x03, 0x01, 0x00, 0x00,
+//! ];
+//!
+//! let (rem, obj1) = parse_ber_integer(&bytes).expect("parsing failed");
+//! let (rem, obj2) = parse_ber_integer(&bytes).expect("parsing failed");
+//! ```
+//!
+//! Parse a BER sequence containing one integer and an octetstring:
+//!
+//! ```rust
+//! use der_parser::ber::*;
+//!
+//! let bytes = [ 0x30, 0x0a,
+//!               0x02, 0x03, 0x01, 0x00, 0x01,
+//!               0x04, 0x03, 0x62, 0x61, 0x64,
+//! ];
+//!
+//! let (rem, seq) = parse_ber_sequence_defined(|content| {
+//!         let (rem, obj1) = parse_ber_integer(content)?;
+//!         let (rem, obj2) = parse_ber_octetstring(rem)?;
+//!         Ok((rem, vec![obj1, obj2]))
+//!     })(&bytes)
+//!     .expect("parsing failed");
+//! ```
