[][src]Derive Macro signature_derive::Signer


Derive the Signer trait for a type which impls [DigestSigner].

When implementing the [DigestSigner] trait for a signature type which itself impl's the [PrehashSignature] trait (which marks signature algorithms which are computed using a Digest), signature providers can automatically derive the Signer trait when the digest algorithm is [PrehashSignature::Digest] (i.e. the "standard" digest algorithm for a given signature type)

This automates all of the digest computation otherwise needed for a complete signature algorithm implementation.
