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".
