Trait jsonway::serializer::ObjectScopeSerializer [−] [src]

pub trait ObjectScopeSerializer<T, S> {
    fn build(&self, _: &T, _: &S, _: &mut ObjectBuilder);

    fn root(&self) -> Option<&str> { ... }

    fn serialize(&mut self, obj: &T, scope: &S, include_root: bool) -> Value { ... }
}

Provides functionality to create custom JSON presenters for your structs.

Example

use jsonway::{self, ObjectScopeSerializer};

struct User {
    id: u64,
    is_admin: bool
}

struct Jedi {
    name: String,
    secret: String
}

struct JediSerializer;

impl jsonway::ObjectScopeSerializer<Jedi, User> for JediSerializer {
    fn root(&self) -> Option<&str> { Some("jedi") }
    fn build(&self, jedi: &Jedi, current_user: &User, json: &mut jsonway::ObjectBuilder) {
        json.set("name", jedi.name.to_string());

        if current_user.is_admin {
            json.set("secret", jedi.secret.to_string());
        }
    }
}

let jedi = Jedi {
    name: "Palpatine".to_string(),
    secret: "Dark side".to_string()
};

let current_user = User { id: 1, is_admin: true };
let json = JediSerializer.serialize(&jedi, &current_user, true);

assert_eq!(
    json.pointer("/jedi/name").unwrap().as_str().unwrap(),
    "Palpatine"
);

assert_eq!(
    json.pointer("/jedi/secret").unwrap().as_str().unwrap(),
    "Dark side"
);
