ActivityStreams Derive
derive macros for ActivityStreams
Usage
Add the required crates to your Cargo.toml
# Cargo.toml
activitystreams = "0.4.0-alpha.3"
serde = { version = "1.0", features = ["derive"] }
And then in your project
// derive macros
use activitystreams::{
properties,
PropRefs,
UnitString
};
// traits
use activitystreams::Object;
// properties
use activitystreams::object::properties::ObjectProperties;
/// 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;
properties! {
My {
docs [
"Using the properties macro",
"",
"This macro generates getters and setters for the associated fields.",
],
kind {
docs [
"Use the UnitString MyKind to enforce the type of the object by \"SomeKind\"",
"",
"Rename to/from 'type' when serializing/deserializing",
],
types [
MyKind,
],
functional,
required,
rename("type"),
},
required_key {
docs [
"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>.",
"",
"'required' here means that the field must be present, otherwise, it's"
"represented as an Option<T>",
],
types [
String,
],
functional,
required,
},
}
}
#[derive(Clone, Default, PropRefs, serde::Deserialize, serde::Serialize)]
#[serde(rename_all = "camelCase")]
pub struct My {
/// Derive AsRef<MyProperties> and AsMut<MyProperties>
#[serde(flatten)]
#[activitystreams(None)]
my_properties: MyProperties,
/// Derive AsRef<ObjectProperties> and AsMut<ObjectProperties>
///
/// as well as the Object trait
#[serde(flatten)]
#[activitystreams(Object)]
properties: ObjectProperties,
}
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut my = My::default();
let mprops: &mut MyProperties = my.as_mut();
mprops.set_required_key("Hello")?;
let mprops: &MyProperties = my.as_ref();
assert_eq!(mprops.get_required_key(), "Hello");
Ok(())
