backbone-integrations 0.6.0

//! Example domain entity
//!
//! Generated by backbone-schema. Do not edit manually.
//!
//! Reference entity showing the canonical layout of a Backbone aggregate:
//! strongly-typed id, FromRow-friendly struct, builder, patch, audit metadata,
//! and the standard trait impls expected by `backbone-core` and `backbone-orm`.
