Required Methods

fn sign<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 K, data: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = Result<BinaryData, ProtocolError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

the public key bytes are only used to look up the private key

fn sign_create_witness<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 K, data: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = Result<AddressWitness, ProtocolError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

the public key bytes are only used to look up the private key

fn can_sign_with(&self, key: &K) -> bool

do we have this identity public key in the signer?

Dyn Compatibility

This trait is dyn compatible.

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