AsyncDigestSigner

signature

Trait AsyncDigestSigner 

Source 
pub trait AsyncDigestSigner<D, S>
where
    D: Update,
{
    // Required method
    async fn sign_digest_async<F: AsyncFn(&mut D) -> Result<(), Error>>(
        &self,
        f: F,
    ) -> Result<S, Error>;
}
Expand description

Asynchronously sign the given prehashed message Digest using Self.

This trait is an async equivalent of the DigestSigner trait.

Required Methods§

Source

async fn sign_digest_async<F: AsyncFn(&mut D) -> Result<(), Error>>( &self, f: F, ) -> Result<S, Error>

Attempt to sign a message by updating the received Digest with it, returning a digital signature on success, or an error if something went wrong.

The given function can be invoked multiple times. It is expected that in each invocation the Digest is updated with the entire equal message.

§Errors

Returns implementation-specific errors in the event signing failed (e.g. KMS or HSM communication error).

Dyn Compatibility§

This trait is not dyn compatible.

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