+//! Traits for Network Representation translation
+//!
+//! The traits found here usually do not need to implemented manually and can be derived using the [`libquassel::NetworkList`] and [`libquassel::NetworkMap`] macros.
+//!
+//! Quassel has 3 main ways to represent an object over the Network:
+//!
+//! ### VariantList
+//! The struct is serialized to a Vector of Variants. This is mostly used in the InitData messages.
+//! First the field name as a ByteArray (UTF-8 String), followed by the field value in it's own Type's va!iant.
+//! The order in which the fields are transmitted cannot be assumed.
+//!
+//! Example:
+//! ```ignore
+//! NetworkConfig {
+//!     ping_timeout_enabled: true,
+//!     ping_interval: 0,
+//! }
+//! ```
+//! to
+//! ```ignore
+//! VariantList([
+//!     ByteArray(
+//!         "pingTimeoutEnabled",
+//!     ),
+//!     bool(
+//!         true,
+//!     ),
+//!     ByteArray(
+//!         "pingInterval",
+//!     ),
+//!     i32(
+//!         30,
+//!     ),
+//! ])
+//! ```
+//!
+//!
+//! ### VariantMap
+//! The struct is represented as a `VariantMap`. The keys and values of
+//! the struct are serialized to a corresponding `HashMap<String, Variant>`.
+//!
+//! Using the [libquassel::NetworkMap] macro this is selected with `#[network(repr = "map")]` on the object.
+//!
+//! Example:
+//! ```ignore
+//! NetworkConfig {
+//!     ping_timeout_enabled: false,
+//!     ping_interval: 0,
+//! }
+//! ```
+//! to
+//! ```ignore
+//! VariantMap({
+//!   "pingTimeoutEnabled": bool(false)
+//!   "pingInterval": i32(0)
+//! })
+//! ```
+//!
+//! ### Structure of Arrays
+//!
+//! For Objects that are transmitted as multiple at once the VariantMap
+//! representation is augemented and instead of transmitting multiple `VariantMaps`,
+//! each field is a `VariantList` of Items.
+//!
+//! Using the [libquassel::NetworkMap] macro this is selected with `#[network(repr = "maplist")]` on the
+//! object.
+//!
+//! Example:
+//! ```ignore
+//! vec![
+//!     NetworkConfig {
+//!         ping_timeout_enabled: false,
+//!         ping_interval: 0,
+//!     },
+//!     NetworkConfig {
+//!         ping_timeout_enabled: true,
+//!         ping_interval: 1,
+//!     },
+//! ]
+//! ```
+//! to
+//! ```ignore
+//! VariantMap({
+//!   "pingTimeoutEnabled": VariantList([
+//!     bool(false),
+//!     bool(true),
+//!   ]),
+//!   "pingInterval": VariantList([
+//!     i32(0),
+//!     i32(1),
+//!   ])
+//! })
+//! ```
