pub trait CredentialStore: Send + Sync {
    // Required methods
    fn set(&self, account: &str, secret: &str) -> Result<(), CredentialError>;
    fn get(&self, account: &str) -> Result<String, CredentialError>;
    fn delete(&self, account: &str) -> Result<(), CredentialError>;

    // Provided method
    fn exists(&self, account: &str) -> bool { ... }
}

The seam between Flow code and the OS keyring (or a test double).
