Light client state signature key with minimal requirements

Required Associated Types

type StatePrivateKey: PrivateSignatureKey

The private key type

type StateSignature: Send + Sync + Sized + Clone + Debug + Eq + Serialize + for<'a> Deserialize<'a> + Hash

The type of the signature

type SignError: Error + Send + Sync

Type of error that can occur when signing data

Required Methods

fn generated_from_seed_indexed( seed: [u8; 32], index: u64, ) -> (Self, Self::StatePrivateKey)

Generate a new key pair

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.

Implementors
