Enum Actor 

#[non_exhaustive]
pub enum Actor {
    User {
        id: i64,
        username: String,
    },
    System {
        process: String,
    },
}

Who is performing a write. Every save states one, so a listener always has a total answer and a missing actor cannot be confused with a non-human write.

Non-exhaustive: an unauthenticated public submission joins when the public web surface gains a write path.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

User

A signed-in operator.

Fields

id: i64

username: String

System

The process itself, named for the trail: seed, job:purge-sessions, lat admin create. Not a stand-in user row.

Fields

process: String
