//! Infrastructure entities for database persistence.
//!
//! This module defines entities that directly map to database tables,
//! providing a clear separation between the persistence layer and the
//! domain layer. These entities represent raw database records without
//! domain validation or business logic.
//!
//! # Conversion Pattern
//!
//! Infrastructure entities implement `TryFrom` traits to convert between
//! database records and domain types:
//!
//! ```rust
//! # use sta::domain::relay::types::{RelayId, RelayLabel};
//! # use sta::infrastructure::persistence::entities::relay_label_record::RelayLabelRecord;
//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
//! // Database Record -> Domain Types
//! // ... from database
//! let record: RelayLabelRecord = RelayLabelRecord { relay_id: 2, label: "label".to_string() };
//! let (relay_id, relay_label): (RelayId, RelayLabel) = record.try_into()?;
//!
//! // Domain Types -> Database Record
//! let domain_record= RelayLabelRecord::new(relay_id, &relay_label);
//! # Ok(())
//! # }
//! ```

/// Database entity for relay labels.
///
/// This module contains the `RelayLabelRecord` struct which represents
/// a single row in the `RelayLabels` database table, along with conversion
/// traits to and from domain types.
