Usage

Basic usage

For basic use, add the following to your Cargo.toml

# Cargo.toml

activitystreams = "0.2"

And then use it in your project

extern crate activitystreams;
extern crate failure;
extern crate serde;
#[macro_use]
extern crate serde_derive;
extern crate serde_json;

use activitystreams::{context, Object, Actor, object::Profile};
use failure::Error;

#[derive(Clone, Debug, Default, Deserialize, Serialize)]
#[serde(rename_all = "camelCase")]
pub struct Persona {
    #[serde(rename = "@context")]
    context: serde_json::Value,

    #[serde(rename = "type")]
    kind: String,
}

impl Object for Persona {}
impl Actor for Persona {}

fn run() -> Result<(), Error> {
    let mut profile = Profile::default();

    profile.profile.set_describes_object(Persona {
        context: serde_json::to_value(context())?,

        kind: "Persona".to_owned(),
    })?;

    profile.object_props.set_context_object(context())?;

    let profile_string = serde_json::to_string(&profile)?;

    let profile: Profile = serde_json::from_str(&profile_string)?;

    Ok(())
}

Advanced Usage

Add the required crates to your Cargo.toml

# Cargo.toml

activitystreams-derive = "0.1"
activitystreams-traits = "0.1"
serde = "1.0"
serde_derive = "1.0"
serde_json = "1.0"

And then in your project

#[macro_use]
extern crate activitystreams_derive;
extern crate activitystreams_traits;
extern crate activitystreams_types;
extern crate failure;
extern crate serde;
#[macro_use]
extern crate serde_derive;
extern crate serde_json;

use activitystreams_traits::{Link, Object};
use activitystreams_types::{CustomLink, link::Mention};
use failure::Error;

/// Using the UnitString derive macro
///
/// This macro implements Serialize and Deserialize for the given type, making this type
/// represent the string "SomeKind" in JSON.
#[derive(Clone, Debug, Default, UnitString)]
#[activitystreams(SomeKind)]
pub struct MyKind;

/// Using the Properties derive macro
///
/// This macro generates getters and setters for the associated fields.
#[derive(Clone, Debug, Default, Deserialize, Serialize, Properties)]
#[serde(rename_all = "camelCase")]
pub struct MyProperties {
    /// Derive getters and setters for @context with Link and Object traits.
    #[serde(rename = "@context")]
    #[activitystreams(ab(Object, Link))]
    pub context: Option<serde_json::Value>,

    /// Use the UnitString MyKind to enforce the type of the object by "SomeKind"
    pub kind: MyKind,

    /// Derive getters and setters for required_key with String type.
    ///
    /// In the Activity Streams spec, 'functional' means there can only be one item for this
    /// key. This means all fields not labeled 'functional' can also be serialized/deserialized
    /// as Vec<T>.
    #[activitystreams(concrete(String), functional)]
    pub required_key: serde_json::Value,
}

fn run() -> Result<(), Error> {
    let mut props = MyProperties::default();

    props.set_required_key_string("Hey".to_owned())?;

    let my_link = CustomLink::new(Mention::default(), props);

    let my_link_string = serde_json::to_string(&my_link)?;

    let my_link: CustomLink<Mention, MyProperties> = serde_json::from_str(&my_link_string)?;

    Ok(())
}
