I have some code that implements this using wrapper types, but would really love for a trait like this to exist: A proposed async-tls-acceptor crate that publishes this trait: ```rust #[async_trait] pub trait Acceptor<Input>: Clone + Send + Sync + 'static where Input: AsyncRead + AsyncWrite + Send + Sync + Unpin + 'static, { type Output: AsyncRead + AsyncWrite + Send + Sync + Unpin + 'static; type Error: std::fmt::Debug + Send + Sync; async fn accept(&self, input: Input) -> Result<Self::Output, Self::Error>; } ``` The implementation for async-native-tls would be: ```rust #[async_trait] impl<Input> Acceptor<Input> for async_native_tls::TlsAcceptor where Input: AsyncRead + AsyncWrite + Send + Sync + Unpin + 'static, { type Output = async_native_tls::TlsStream<Input>; type Error = async_native_tls::Error; async fn accept(&self, input: Input) -> Result<Self::Output, Self::Error> { async_native_tls::TlsAcceptor::accept(&self, input).await } } ``` Would this be welcomed? refs: https://github.com/async-rs/async-tls/issues/43
