Trait RecoverableSignPrimitive 

pub trait RecoverableSignPrimitive<C>
where
    C: PrimeCurve + ProjectiveArithmetic,
    SignatureSize<C>: ArrayLength<u8>,
{
    // Required method
    fn try_sign_recoverable_prehashed<K: Borrow<Scalar<C>> + Invert<Output = Scalar<C>>>(
        &self,
        ephemeral_scalar: &K,
        hashed_msg: &Scalar<C>,
    ) -> Result<(Signature<C>, bool)>;
}

Available on crate features hazmat and arithmetic only.

SignPrimitive for signature implementations that can provide public key recovery implementation.

Required Methods

fn try_sign_recoverable_prehashed<K: Borrow<Scalar<C>> + Invert<Output = Scalar<C>>>( &self, ephemeral_scalar: &K, hashed_msg: &Scalar<C>, ) -> Result<(Signature<C>, bool)>

Try to sign the prehashed message.

Accepts the same arguments as SignPrimitive::try_sign_prehashed but returns a boolean flag which indicates whether or not the y-coordinate of the computed 𝐑 = 𝑘×𝑮 point is odd, which can be incorporated into recoverable signatures.

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.
