pub trait SigningProvider: Debug {
    // Required methods
    fn client_email(&self) -> impl Future<Output = Result<String>> + Send;
    fn sign(&self, content: &[u8]) -> impl Future<Output = Result<Bytes>> + Send;
}

A trait for types that can sign content.

Required Methods

fn client_email(&self) -> impl Future<Output = Result<String>> + Send

It is typically the Google service account client email address from the Google Developers Console in the form of “xxx@developer.gserviceaccount.com”.

Signs the content.

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
