Listen-kit as a local dependecy, from sources, won't build in referencing project

[dandagow3t]

Description

I've added listen-kit as a local dependency to my project Cargo.toml

listen-kit = { path = "../listen/listen-kit"}

but I'm unable to build through:

error: future cannot be sent between threads safely

error: could not compile `listen-kit` (lib) due to 1 previous error

Steps to Reproduce

1. Create a new project cargo new test_listen_kit
2. Add listen-kit as a new dependency in Cargo.toml

[dependencies]
listen-kit = { path = "../listen/listen-kit" }

also, tried with all combinations of features (http, solana, or both) 3. Run

cargo build

Additional Notes

No response

[dandagow3t]

The root cause here is how features are being handled across both crates. In listen-kit, the default feature is set to ["http"]. When you reference listen-kit from your project with the solana feature, both http and solana features end up being activated simultaneously. This combination is causing the compilation error you encountered. The solution is to modify listen-kit's default feature to be ["solana"] instead of ["http"]. This change would prevent both features from being activated unintentionally when you reference the crate in your project.

What's weird is that listen-kit compiles just fine on it's own with both features (http & solana) activated.
