Available on crate feature tls only.

A dynamic TLS configuration resolver.

Example

This is an async trait. Implement it as follows:

use std::sync::Arc;
use rocket::tls::{self, Resolver, TlsConfig, ClientHello, ServerConfig};
use rocket::{Rocket, Build};

struct MyResolver(Arc<ServerConfig>);

#[rocket::async_trait]
impl Resolver for MyResolver {
    async fn init(rocket: &Rocket<Build>) -> tls::Result<Self> {
        // This is equivalent to what the default resolver would do.
        let config: TlsConfig = rocket.figment().extract_inner("tls")?;
        let server_config = config.server_config().await?;
        Ok(MyResolver(Arc::new(server_config)))
    }

    async fn resolve(&self, hello: ClientHello<'_>) -> Option<Arc<ServerConfig>> {
        // return a `ServerConfig` based on `hello`; here we ignore it
        Some(self.0.clone())
    }
}

#[launch]
fn rocket() -> _ {
    rocket::build().attach(MyResolver::fairing())
}
