dynamic-config-actix

A request-scoped dynamic-config snapshot for Actix Web: one middleware, one extractor.

[dependencies]
dynamic-config-actix = "0.2.0"

use dynamic_config_actix::{Config, DynamicConfig};
use dynamic_config_web_core::sections;

#[get("/")]
async fn index(server: Config<Server>, features: Config<Features>) -> String {
    format!("{} {}", server.port, features.cache)
}

App::new()
    .wrap(DynamicConfig::new(sections![Server, Features]))
    .service(index);

Both sections come from one reading taken when the request began, so a reload landing mid-request cannot show one response two generations.

The middleware owns no lifecycle: loading, watching and the WatchHandle stay in your main, unchanged.

See the workspace README for the problem this solves, and cargo run -p dynamic-config-actix --example actix_two_sections for a runnable demonstration.
