//! Default value example for the oximod crate
//!
//! Run with: `cargo run --example default_usage`
//!
//! This demonstrates how to:
//! - Use `#[default(...)]` to assign default values to fields
//! - Customize `_id` setter via `#[document_id_setter_ident(...)]`
//! - Use enum and scalar defaults
//! - Build a model using the fluent API
