Attribute Macro activitystreams::wrapper_type

#[wrapper_type]

Derive a wrapper type based on serde_json::Value to contain any possible trait type

The following code

#[wrapper_type]
pub trait Object {}

produces the following type

pub struct ObjectBox(pub serde_json::Value);

impl ObjectBox {
    pub fn from_concrete<T>(t: T) -> Result<Self, std::io::Error>
    where
        T: Object + serde::ser::Serialize;

    pub fn into_concrete<T>(self) -> Result<T, std::io::Error>
    where
        T: Object + serde::de::DeserializeOwned;

    pub fn is_type(&self, kind: impl std::fmt::Display) -> bool;

    pub fn type(&self) -> Option<&str>;
}
