    // Required methods

        &'life0 self,

             'life1: 'async_trait;
}

A signer for a validator.

Required Associated Types

type ValidatorId: ValidatorId

type Signature: Signature

Signature type.

Required Methods

fn validator_id<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<Self::ValidatorId>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns the validator’s current ID. Returns None if they aren’t a current validator.

fn sign<'life0, 'life1, 'async_trait>( &'life0 self, msg: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Self::Signature> + Send + 'async_trait>>

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

Sign a signature with the current validator’s private key.

Dyn Compatibility

This trait is dyn compatible.

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