//! # ActivityStreams New
//! __A set of Traits and Types that make up the ActivityStreams and ActivityPub specifications__
//!
//! ## Usage
//!
//! First, add ActivityStreams to your dependencies
//! ```toml
//! [dependencies]
//! activitystreams-new = { git = "https://git.asonix.dog/asonix/activitystreams-sketch" }
//! ```
//!
//! ### Types
//!
//! The project is laid out by Kind => Type
//!
//! So to use an ActivityStreams Video, you'd write
//! ```rust
//! use activitystreams_new::object::Video;
//! let video = Video::new();
//! ```
//!
//! And to use an ActivityPub profile, you'd write
//! ```rust
//! use activitystreams_new::object::{ApObject, Profile};
//! let inner = Profile::new();
//! let profile = ApObject::new(inner);
//! ```
//!
//! There's only one kind of Link
//! ```rust
//! use activitystreams_new::link::Mention;
//! let mention = Mention::new();
//! ```
//!
//! ### Fields
//!
//! Many fields on the provided types are wrapped in `OneOrMany<>` or have a type of `AnyBase`. This
//! is because the activitystreams spec is very open as to what is considered a valid structure.
//!
//! For example, the Object type in ActivityStreams has a `summary` field, which can either be
//! represented as an `xsd:string` or an `rdf:langString`. It also states that the `summary` field
//! is not `functional`, meaning that any number of `xsd:string` or `rdf:langString`, or a
//! combination thereof, can be present. This library represents this as `Option<OneOrMany<AnyString>>`.
//!
//! This resulting type is exactly specific enough to match the following valid ActivityStreams
//! json, without matching any invalid json.
//!
//! With no summary:
//! ```json
//! {}
//! ```
//!
//! With a sring summary:
//! ```json
//! {
//!     "summary": "A string"
//! }
//! ```
//!
//! With an rdf langstring
//! ```json
//! {
//!     "summary": {
//!         "@value": "A string",
//!         "@language": "en"
//!     }
//! }
//! ```
//!
//! With multiple values
//! ```json
//! {
//!     "summary": [
//!         {
//!             "@value": "A string",
//!             "@language": "en"
//!         },
//!         "An xsd:string this time"
//!     ]
//! }
//! ```
//!
//! It may seem like interacting with these types might get unweildy, there are some custom methods
//! implemented on the `OneOrMany` type depending on what's inside of it.
//!
//! ```rust,ignore
//! fn from_xsd_string<T>(&mut self, T) -> Self;
//! fn from_rdf_lang_string<T>(&mut self, T) -> Self;
//!
//! fn as_single_xsd_string(&self) -> Option<&XsdString>;
//! fn as_single_rdf_langstring(&self) -> Option<&RdfLangString>;
//!
//! fn single_xsd_string(self) -> Option<XsdString>;
//! fn single_rdf_lang_string(self) -> Option<RdfLangString>;
//!
//! fn add_xsd_string<T>(&mut self, T) -> &mut Self;
//! fn add_rdf_lang_string<T>(&mut self, T) -> &mut Self;
//! ```
//! These methods provide access to setting and fetching uniformly typed data, as well as deleting
//! the data. In the setter methods, the type parameter T is bound by
//! `Into<XsdString>` or `Into<RdfLangString>`. This allows passing values to the method that
//! can be converted into the types, rather than requiring the caller to perform the conversion.
//!
//! Types like `XsdString` and `RdfLangString` can be found in the `primitives` module. Unless
//! you're building your own custom types, you shouldn't need to import them yourself. They each
//! implement `FromStr` for parsing and `Display` to convert back to strings, as well as `From` and
//! `Into` or `TryFrom` and `TryInto` for types you might expect them to (e.g.
//! `XsdNonNegativeInteger` implements `From<u64>` and `Into<u64>`).
//!
//! ### Traits
//!
//! Since ActivityStreams is a heirarchical structure of data, it's represented as structs containing
//! other structs. This means that the `context` field, which can be present on any ActivityStreams type,
//! will be located in the innermost struct. In order to avoid writing code like
//! `ap_object.collection.object.base.context = Some(context())`, this library provides traits that are
//! automatically implmeneted for provided types.
//!
//! For example, the `BaseExt` trait provides the following methods for `context`,
//! ```rust,ignore
//! fn context(&self) -> Option<&OneOrMany<AnyBase>>;
//!
//! fn set_context<T>(&mut self, context: T) -> &mut Self
//! where
//!     T: Into<AnyBase>;
//!
//! fn set_many_contexts<I, T>(&mut self, items: I) -> &mut Self
//! where
//!     I: IntoIterator<Item = T>,
//!     T: Into<AnyBase>;
//!
//! fn add_context<T>(&mut self, context: T) -> &mut Self
//! where
//!     T: Into<AnyBase>;
//!
//! fn take_context(&mut self) -> Option<OneOrMany<AnyBase>>;
//! fn delete_context(&mut self) -> &mut Self;
//! ```
//!
//! For fields with more specific bounds, like `id`,
//! ```rust,ignore
//! fn id(&self) -> Option<&XsdAnyUri>;
//! fn set_id(&mut self, XsdAnyUri) -> &mut Self;
//! fn take_id(&self) -> Option<XsdAnyUri>;
//! fn delete_id(&mut self) -> &mut Self;
//! ```
//!
//! The full list of extension traits that implement methods like these on types can be found in the
//! prelude module. By using `use activitystreams_new::prelude::*;` all of the methods will be
//! implemented for types containing their fields.
//!
//! ### Markers
//!
//! This library provides a number of traits, such as `Object`, `Link`, `Actor`, `Activity`,
//! `Collection`, and `CollectionPage`. The majority of these traits exist solely to "mark" types,
//! meaning they don't provide value, at runtime, but exist to add constraints to generics at
//! compiletime.
//!
//! If you want to make a function that manipulates an Activity, but not a normal object, you could
//! bound the function like so:
//!
//! ```rust
//! use activitystreams_new::{base::BaseExt, context, markers::Activity};
//!
//! fn manipulator<T, Kind>(mut activity: T) -> Result<(), anyhow::Error>
//! where
//!     T: Activity + BaseExt<Kind>,
//! {
//!     activity
//!         .set_id("https://example.com".parse()?)
//!         .set_context(context());
//!     Ok(())
//! }
//! ```
//!
//! ### Kinds
//!
//! This library has a set of unit structs that serialize and deserialize to strings. This is to
//! enable different ActivityPub Object types to be deserialized into different Named structs.
//! These can be found in `activitystreams_new::objects::kind`, and similar paths.
//!
//! To build your own Person struct, for example, you could write
//! ```rust
//! use activitystreams_new::actor::kind::PersonType;
//!
//! #[derive(serde::Deserialize, serde::Serialize)]
//! pub struct MyPerson {
//!     // Do a rename since `type` is not a valid rust field name
//!     #[serde(rename = "type")]
//!     kind: PersonType,
//! }
//! ```
//! And this type would only deserialize for JSON where `"type":"Person"`
//!
//! ## Examples
//!
//! ### Create
//!
//! ```rust
//! use activitystreams_new::{
//!     context,
//!     object::{ApObject, Video},
//!     prelude::*,
//!     primitives::{XsdAnyUri, XsdString},
//! };
//!
//! fn main() -> Result<(), anyhow::Error> {
//!     let mut video = ApObject::new(Video::new());
//!
//!     video
//!         .set_context(context())
//!         .set_id("https://example.com/@example/lions".parse()?)
//!         .set_media_type("video/webm".parse()?)
//!         .set_url("https://example.com/@example/lions/video.webm".parse::<XsdAnyUri>()?)
//!         .set_summary(XsdString::from("A cool video"))
//!         .set_duration("PT4M20S".parse()?)
//!         .set_shares("https://example.com/@example/lions/video.webm#shares".parse()?);
//!
//!     println!("Video, {:#?}", video);
//!
//!     let s = serde_json::to_string(&video)?;
//!
//!     println!("json, {}", s);
//!
//!     let v: ApObject<Video> = serde_json::from_str(&s)?;
//!
//!     println!("Video again, {:#?}", v);
//!
//!     Ok(())
//! }
//! ```
//!
//! ### Parse
//!
//! ```rust
//! use activitystreams_new::{activity::ActorAndObject, prelude::*};
//!
//! #[derive(Clone, Debug, serde::Deserialize, serde::Serialize)]
//! pub enum AcceptedTypes {
//!     Accept,
//!     Announce,
//!     Create,
//!     Delete,
//!     Follow,
//!     Reject,
//!     Update,
//!     Undo,
//! }
//!
//! pub type AcceptedActivity = ActorAndObject<AcceptedTypes>;
//!
//! pub fn handle_activity(activity: AcceptedActivity) -> Result<(), anyhow::Error> {
//!     println!("Actor: {:?}", activity.actor());
//!     println!("Object: {:?}", activity.object());
//!
//!     match activity.kind() {
//!         Some(AcceptedTypes::Accept) => println!("Accept"),
//!         Some(AcceptedTypes::Announce) => println!("Announce"),
//!         Some(AcceptedTypes::Create) => println!("Create"),
//!         Some(AcceptedTypes::Delete) => println!("Delete"),
//!         Some(AcceptedTypes::Follow) => println!("Follow"),
//!         Some(AcceptedTypes::Reject) => println!("Reject"),
//!         Some(AcceptedTypes::Update) => println!("Update"),
//!         Some(AcceptedTypes::Undo) => println!("Undo"),
//!         None => return Err(anyhow::Error::msg("No activity type provided")),
//!     }
//!
//!     Ok(())
//! }
//!
//! static EXAMPLE_JSON: &str = r#"{"actor":"https://asonix.dog/users/asonix","object":"https://asonix.dog/users/asonix/posts/1","type":"Announce"}"#;
//!
//! fn main() -> Result<(), anyhow::Error> {
//!     handle_activity(serde_json::from_str(EXAMPLE_JSON)?)
//! }
//! ```
