openzeppelin_relayer/models/relayer/
config.rs

1//! Configuration file representation and parsing for relayers.
2//!
3//! This module handles the configuration file format for relayers, providing:
4//!
5//! - **Config Models**: Structures that match the configuration file schema
6//! - **Validation**: Config-specific validation rules and constraints
7//! - **Conversions**: Bidirectional mapping between config and domain models
8//! - **Collections**: Container types for managing multiple relayer configurations
9//!
10//! Used primarily during application startup to parse relayer settings from config files.
11//! Validation is handled by the domain model in mod.rs to ensure reusability.
