Trait BlockSigner 

pub trait BlockSigner {
    type Error: Error + Send + Sync + 'static;

    // Required methods
    fn sign(
        &self,
        header: &BlockHeader,
    ) -> impl Future<Output = Result<Signature, Self::Error>> + Send;
    fn public_key(&self) -> PublicKey;
}

Trait which abstracts the signing of block headers with ECDSA signatures.

Production-level implementations will involve some sort of secure remote backend. The trait also allows for testing with local and ephemeral signers.

Required Associated Types

type Error: Error + Send + Sync + 'static

Required Methods

fn sign( &self, header: &BlockHeader, ) -> impl Future<Output = Result<Signature, Self::Error>> + Send

fn public_key(&self) -> PublicKey

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.
