This crate provides Ext1, Ext2, Ext3, and Ext4 for adding extensions to ActivityStreams types
First, add ActivityStreams to your dependencies
toml
[dependencies]
activitystreams = "0.7.0-alpha.3"
activitystreams-ext = "0.1.0-alpha.2"
For an example, we'll implement a PublicKey extension and demonstrate usage with Ext1 ```rust use activitystreams_ext::{Ext1, UnparsedExtension}; use activitystreams::{ actor::{ApActor, Person}, context, prelude::*, primitives::XsdAnyUri, security, unparsed::UnparsedMutExt, };
pub struct PublicKey { public_key: PublicKeyInner, }
pub struct PublicKeyInner { id: XsdAnyUri, owner: XsdAnyUri, publickeypem: String, }
impl UnparsedExtension for PublicKey where U: UnparsedMutExt, { type Error = serde_json::Error;
fn try_from_unparsed(unparsed_mut: &mut U) -> Result<Self, Self::Error> {
Ok(PublicKey {
public_key: unparsed_mut.remove("publicKey")?,
})
}
fn try_into_unparsed(self, unparsed_mut: &mut U) -> Result<(), Self::Error> {
unparsed_mut.insert("publicKey", self.public_key)?;
Ok(())
}
}
pub type ExtendedPerson = Ext1
fn main() -> Result<(), anyhow::Error> { let actor = ApActor::new( "http://in.box".parse()?, "http://out.box".parse()?, Person::new(), );
let mut person = Ext1::new(
actor,
PublicKey {
public_key: PublicKeyInner {
id: "http://key.id".parse()?,
owner: "http://owner.id".parse()?,
public_key_pem: "asdfasdfasdf".to_owned(),
},
},
);
person.set_context(context()).add_context(security());
let any_base = person.into_any_base()?;
println!("any_base: {:#?}", any_base);
let person = ExtendedPerson::from_any_base(any_base)?;
println!("person: {:#?}", person);
Ok(())
} ```
