Expand description

A type family of public keys that are used for signing.

This trait has a requirement on a pub(crate) marker trait meant to specifically limit its implementations to the present crate.

It is linked to a type of the Signature family, which carries the verification implementation.

Required Associated Types§

Source

type SigningKeyMaterial: SigningKey<VerifyingKeyMaterial = Self>

The associated signing key type for this verifying key.

Source

type SignatureMaterial: Signature<VerifyingKeyMaterial = Self>

The associated signature type for this verifying key.

Provided Methods§

Source

fn verify_struct_signature<T: CryptoHash + Serialize>( &self, message: &T, signature: &Self::SignatureMaterial, ) -> Result<()>

We provide the striaghtfoward implementation which dispatches to the signature.

Source

fn batch_verify<T: CryptoHash + Serialize>( message: &T, keys_and_signatures: Vec<(Self, Self::SignatureMaterial)>, ) -> Result<()>

We provide the implementation which dispatches to the signature.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
