Trait Recoverable 

Source 
pub trait Recoverable: Signature {
    type PublicKey: PublicKey<Signature = Self>;

    // Required method
    fn recover_signer(
        &self,
        namespace: &[u8],
        msg: &[u8],
    ) -> Option<Self::PublicKey>;
}
Expand description

An extension of Signature that supports public key recovery.

Required Associated Types§

Source

type PublicKey: PublicKey<Signature = Self>

The type of PublicKey that can be recovered from this Signature.

Required Methods§

Source

fn recover_signer( &self, namespace: &[u8], msg: &[u8], ) -> Option<Self::PublicKey>

Recover the PublicKey of the signer that created this Signature over the given message.

The message should not be hashed prior to calling this function. If a particular scheme requires a payload to be hashed before it is signed, it will be done internally.

Like when verifying a signature, the namespace must match what was used during signing exactly.

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.
