I'm not sure what tokio (or axum) can do to avoid the trait bounds. Would it makes sense to provide a "share nothing" runtime implementation that can be injected at startup? I wonder how the intermediate layers (e.g. axum) would indicate that futures are usable by a more generic runtime which may or may not need
Send + 'static
.Without some way to write generic code for either runtime, the whole tokio ecosystem would end up bifurcated by this choice of runtime.
Isn't this
tokio::task::spawn_local
?Not exactly. I'm talking specifically about being able to call
axum::serve
with non-Send futures.
