Trait tor_checkable::SelfSigned

pub trait SelfSigned<T>: Sized {
    type Error;

    // Required methods
    fn is_well_signed(&self) -> Result<(), Self::Error>;
    fn dangerously_assume_wellsigned(self) -> T;

    // Provided method
    fn check_signature(self) -> Result<T, Self::Error> { ... }
}

A cryptographically signed object that can be validated without additional public keys.

It’s better to wrap things in a SelfSigned than to give them an is_valid() method, so that you can make sure that nobody uses the object before checking it. It’s better to wrap things in a SelfSigned than to check them immediately, since you might want to defer the signature checking operation to another thread.

Required Associated Types

type Error

An error type that’s returned when the object is not well-signed.

Required Methods

fn is_well_signed(&self) -> Result<(), Self::Error>

Check the signature on this object

fn dangerously_assume_wellsigned(self) -> T

Return the underlying object without checking its signature.

Provided Methods

fn check_signature(self) -> Result<T, Self::Error>

Unwrap this object if the signature is valid

Object Safety

This trait is not object safe.
