HTTP client

Corvis does not include an HTTP client module (an injectable service for calling other APIs with per-module configuration).

Alternative

Use a Rust HTTP client, such as reqwest, and share it as a provider. A client of this kind keeps a connection pool, so it is best to create a single instance:

#[module(
    providers = [
        Provider::use_factory("HTTP_CLIENT", |_ctx| async move {
            Ok(reqwest::Client::builder().timeout(std::time::Duration::from_secs(5)).build()?)
        }),
        PaymentsService,
    ],
)]
pub struct PaymentsModule;

#[injectable]
pub struct PaymentsService {
    #[inject("HTTP_CLIENT")]
    http: Arc<reqwest::Client>,
}

reqwest is not a Corvis dependency: add it to your Cargo.toml. Provider::use_factory and #[inject("TOKEN")] are explained in Custom providers.
