Struct AppCredentials 

pub struct AppCredentials {
    pub app_id: String,
    pub key_bytes: Zeroizing<Vec<u8>>,
}

The two halves of the App identity. The caller resolves both — the id from the environment, the key from the run’s one read of the named file — so this module never opens anything itself.

Fields

app_id: String

The numeric App id, which becomes the token’s iss.

key_bytes: Zeroizing<Vec<u8>>

The validated private key’s bytes.
