middleware tuple compile errors #192

Closed rts-gordon closed 3 years ago

rts-gordon commented 3 years ago

Hi @trezm I compile the lastest code from master branch, there are some errors, can you please have a look at those:

error[E0599]: the method `middleware` exists for tuple `(fn(T, Box<(dyn FnOnce(T) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>> + Sync + std::marker::Send + 'static)>) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>>, fn(T, Box<(dyn FnOnce(T) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>> + Sync + std::marker::Send + 'static)>) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>>, fn(T, Box<(dyn FnOnce(T) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>> + Sync + std::marker::Send + 'static)>) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>>, fn(T, Box<(dyn FnOnce(T) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>> + Sync + std::marker::Send + 'static)>) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>>, fn(T, Box<(dyn FnOnce(T) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>> + Sync + std::marker::Send + 'static)>) -> Pin<Box<(dyn futures::Future<Output = Result<T, ThrusterError<T>>> + Sync + std::marker::Send + 'static)>>)`, but its trait bounds were not satisfied

A few things need to be updated, the working branch is here: https://github.com/thruster-rs/Thruster/pull/193. I just need to clean up some of the alternative servers before I can merge it in.

This should be resolved by https://github.com/thruster-rs/Thruster/releases/tag/v1.1.9! Let me know if you're still having issues.
