Crate id_token_verifier 

🔎 id_token_verifier ✅

A feature-rich, highly configurable OpenID Connect ID token verifier in Rust — empowering you to validate ID tokens as easily as this, while handling retries, caching, and more under the hood:

use id_token_verifier::*;
use id_token_verifier::client::*;

#[derive(serde::Deserialize)]
struct MyClaims {
    sub: String,
    email: Option<String>,
    email_verified: Option<bool>,
}

async fn verify(
    token: &str,
    id_token_verifier: &IdTokenVerifierDefault
) -> Result<MyClaims, IdTokenVerifierError> {
    id_token_verifier.verify(token).await
}

✨ Features

• 🔁 Configurable JWKS caching, including background refresh.
• 🛠 Pluggable retry logic via backoff_config and backon.
• ⚙️ Flexible validation settings.
• 🧩 serde-friendly configuration — load from config files or environment variables, or use the provided config Builders.
• 📈 tracing support via the optional tracing feature flag.
