Compiler error while compiling the k256 library

[BosonicJustin]

The compiler error is caused by the line self.0.sign_digest(Digest::new_with_prefix(digest_bytes)) and self.0.sign_digest(Digest::new()) (commented out in the provided code for testing).

Code

use k256::ecdsa::{Signature, SigningKey, signature::{DigestSigner, DigestVerifier}};
use sha3::{Digest, Keccak256};

struct SignatureECDSA(SigningKey);

impl SignatureECDSA {
    pub fn generate() -> Self {
        Self(SigningKey::random(&mut rand::thread_rng()))
    }

    pub fn new(signing_key: SigningKey) -> Self {
        Self(signing_key)
    }

    pub fn sign(&self, digest_bytes: &[u8; 32]) -> Signature {
        // self.0.sign_digest(Digest::new())

        self.0.sign_digest(Digest::new_with_prefix(digest_bytes))
    }
}

I can't reproduce this; on both stable and nightly, I get the error

error[E0790]: cannot call associated function on trait without specifying the corresponding `impl` type

Can you check if you still get this issue after a cargo clean, and specify any crates + features used?

I believe this is a duplicate of #135410

[jieyouxu]

Hi @BosonicJustin, could you check if this repros against 1.84.1?

[jieyouxu]

I believe this is a duplicate of #135410 whose fix should have been backported to stable 1.84.1. I'm going to close this, but please re-open if this is still a problem.
