Trait async_signature::AsyncDigestSigner

pub trait AsyncDigestSigner<D, S> where
    Self: Send + Sync,
    D: Digest + Send + 'static,
    S: Signature + 'static, {
    fn sign_digest_async<'life0, 'async_trait>(
        &'life0 self, 
        digest: D
    ) -> Pin<Box<dyn Future<Output = Result<S, Error>> + Send + 'async_trait>>
    where
        'life0: 'async_trait,
        Self: 'async_trait;
}

This is supported on crate feature digest only.

Asynchronously sign the given prehashed message Digest using Self.

This trait is an async equivalent of the signature::DigestSigner trait.

Required methods

fn sign_digest_async<'life0, 'async_trait>(
    &'life0 self,
    digest: D
) -> Pin<Box<dyn Future<Output = Result<S, Error>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Attempt to sign the given prehashed message Digest, returning a digital signature on success, or an error if something went wrong.

impl<D, S, T> AsyncDigestSigner<D, S> for T where
    D: Digest + Send + 'static,
