//! Database Backend Abstractions
//!
//! This module provides database backend abstractions to support multiple database types
//! (PostgreSQL, MySQL, SQLite, etc.) through common traits and interfaces.

pub mod core;
pub mod postgres;

// Re-export core traits and types
pub use core::*;
pub use postgres::PostgresBackend;

/// Database backend type enumeration
#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub enum DatabaseBackendType {
    PostgreSQL,
    MySQL,
    SQLite,
}

    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        match self {
            DatabaseBackendType::PostgreSQL => write!(f, "postgresql"),
            DatabaseBackendType::MySQL => write!(f, "mysql"),
            DatabaseBackendType::SQLite => write!(f, "sqlite"),
        }
    }
