remove Send and Sync bounds from Rust SDK router

[dicej]

These bounds were preventing users from calling async functions which use http::executor since it uses Rc<RefCell<_>> internally, which is neither Send nor Sync.

I still got the same error with

# spin --version
spin 2.2.0-pre0 (a1a82c9c 2023-12-22)

I build from source now. So my spin has this merge in.

@seungjin The version of Spin you use doesn't matter in this case -- it's the spin_sdk version that matters. Would you please double-check that you're using a version of spin_sdk that contains this fix?

[seungjin]

In my Cargo.toml

spin-sdk = { git = "https://github.com/fermyon/spin", branch = "main" }

Did cargo clean, spin build

[seungjin]

Did with (in my Cargo.toml)

spin-sdk = { git = "https://github.com/fermyon/spin", rev = "10ec302282896cdbc2860fc8beaebba7c01c72af" }

and compile was succeeded!!

[seungjin]

Isn't the code in the main branch??
Not working with branch = main but works with rev = "10ec30228...." ?

[dicej]

The main branch has it. You may need to run cargo update to force cargo to fetch the latest code and update your Cargo.lock file.

[seungjin]

Yep. Figured out it is lock file. Working back now.
Thanks for fixing this issue!!!

[seungjin]

Compile was succeed and I deployed and tested.
But I don't get actually outbound http request's response to print.

[seungjin]

Never mind.. Working.. had two spin running.. some indirection happened.
