Struct Entity 

pub struct Entity<T>(pub MorphAddr, pub T)
where
    T: Clone;

A distinct state within the context of a life-cycle

A MorphAddr and its entry content represent a chain in the entity’s life-cycle.

Example: Basic Usage

    ActionHash, TryFrom,
};
    Entity, MorphAddr,
};

#[derive(Clone)]
struct Content {
    pub message: String,
}

let identity_addr = "uhCkkrVjqWkvcFoq2Aw4LOSe6Yx9OgQLMNG-DiXqtT0nLx8uIM2j7";
let revision_addr = "uhCkknDrZjzEgzf8iIQ6aEzbqEYrYBBg1pv_iTNUGAFJovhxOJqu0";

Entity::<Content>(
    MorphAddr(
        ActionHash::try_from(identity_addr).unwrap(),
        ActionHash::try_from(revision_addr).unwrap(),
    ),
    Content {
        message: String::from("Hello world"),
    }
);

Tuple Fields

0: MorphAddr

The Metamorphic address relevant to T (the content)

1: T

The content that belong’s to the MorphAddr’s revision address
