Pull Request Overview

This PR enhances the DNS resolver module by introducing a more ergonomic trait-based API (IntoResolve) that enables easier conversion of various resolver types into the expected Arc<dyn Resolve> format. The changes simplify the user experience when working with DNS resolvers by providing automatic conversions and removing the need for explicit Arc wrapping or error handling for domain name parsing.

• Introduced IntoResolve trait for ergonomic conversion of resolver types to Arc<dyn Resolve>
• Replaced fallible FromStr implementation for Name with infallible From<&str> implementation
• Updated API signatures to accept generic resolver types through the new trait
