Trait Signer 

pub trait Signer {
    type Validator: Validator;
    type Signature: Signature;
    type SignFuture: Future<Output = Self::Signature>;

    // Required methods
    fn validator(&self) -> Self::Validator;
    fn sign(
        &self,
        message: impl IntoIterator<Item = impl AsRef<[u8]>>,
    ) -> Self::SignFuture;
}

A signer for a validator.

Required Associated Types

type Validator: Validator

The type used to identify validators.

type Signature: Signature

The type used to represent signatures.

type SignFuture: Future<Output = Self::Signature>

The future yielded by Signer::sign.

This DOES NOT need to be cancel-safe.

Required Methods

fn validator(&self) -> Self::Validator

This validator’s ID.

This MUST be consistent and not change across multiple invocations.

fn sign( &self, message: impl IntoIterator<Item = impl AsRef<[u8]>>, ) -> Self::SignFuture

Sign a signature as this validator.

The message is the concatenation of each byte slice yielded by the iterator.

Dyn Compatibility

This trait is not dyn compatible.

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