Module server_config 

Typed server configuration.

ServerConfig holds all per-instance configuration fields as typed Rust values. It replaces point-of-use env::var("RWS_CONFIG_*") calls with a struct that can be:

• Built from environment variables once at startup: ServerConfig::from_env()
• Constructed directly in tests without touching the environment: ServerConfig::default() / struct update syntax
• Passed to [App::with_config] to create a fully isolated application instance — essential for parallel tests and embedded multi-tenant use

Test isolation example

use rust_web_server::app::App;
use rust_web_server::server_config::ServerConfig;
use rust_web_server::test_client::TestClient;

// No env writes, no lock needed.
let app = App::with_config(ServerConfig {
    cors_allow_all: false,
    cors_allow_origins: "https://example.com".to_string(),
    ..ServerConfig::default()
});
let client = TestClient::new(app);
let res = client.get("/").send();
