Trait RecoverableSigner 

pub trait RecoverableSigner<C: RecoverableCurve>: Signer<C> + Send {
    // Required method
    fn sign_recoverable(
        &self,
        msg: &[u8],
    ) -> impl Future<Output = Result<(C::Signature, C::RecoveryId), Self::Error>> + Send;
}

A Signer that can produce recoverable signatures.

Required Methods

fn sign_recoverable( &self, msg: &[u8], ) -> impl Future<Output = Result<(C::Signature, C::RecoveryId), Self::Error>> + Send

Sign a given message and return a signature along with recovery id.

NOTE: implementations MAY require msg to be prehash (i.e. output of cryptographic hash function) of a fixed length and return an error otherwise. Check corresponding docs before using.

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.

Implementations on Foreign Types

impl RecoverableSigner<Secp256k1> for SigningKey

async fn sign_recoverable( &self, prehash: &[u8], ) -> Result<(<Secp256k1 as Curve>::Signature, <Secp256k1 as RecoverableCurve>::RecoveryId), Self::Error>

Sign 32-byte prehash (i.e. output of cryptographic hash function) and return a signature along with recovery id.

If given prehash is of different length, an error will be returned.
