Struct DatabaseSettings 

pub struct DatabaseSettings {
    pub backend: DbBackend,
    pub url: Option<String>,
    pub host: Option<String>,
    pub port: Option<u16>,
    pub dbname: Option<String>,
    pub user: Option<String>,
    pub password_file: Option<PathBuf>,
}

Which database backend modde stores its state in, plus the PostgreSQL connection parameters (used only when backend = "postgres").

Every field is #[serde(default)], so existing config files round-trip and default to SQLite. Environment variables override these at startup (MODDE_DATABASE_BACKEND, MODDE_DATABASE_URL, the discrete MODDE_DATABASE_HOST/PORT/NAME/USER fields, and MODDE_DB_PASSWORD_FILE) so the Home Manager module can configure the backend declaratively without rewriting settings.toml. The PostgreSQL password is never stored here — it is read at runtime from password_file.

Fields

backend: DbBackend

url: Option<String>

Full connection URL (e.g. postgres://user@host/db). Takes precedence over the discrete host/port/dbname/user fields when set.

host: Option<String>

port: Option<u16>

dbname: Option<String>

Database name. The matching environment variable is MODDE_DATABASE_NAME, not MODDE_DATABASE_DBNAME.

user: Option<String>

password_file: Option<PathBuf>

Path to a file containing the PostgreSQL password (sops-nix compatible). Read at runtime; never written back to settings.toml.
