doc: MSRV?

[maflcko]

Just wondering if there is a minimum supported version and if it can be documented

[maflcko]

Ah, found it 😅

worst-executor/src/lib.rs

Line 19 in ea0f8ee

//! Currently this library requires rust *nightly* for the `pin` macro, the `join` macro(used in tests) and the `const_waker` feature (required for complete optimization of `block_on`)

[elichai]

Hehe yeah, everything here is ~1.36 but the compiler optimizations are much less effective if I don't make the Waker a const, and that requires either nightly (because Waker::from_raw is const unstable) or relying on implementation details and transmuting the RawWaker to a Waker

[elichai]

I also hope that by me using nightly for these things it could hopefully help to push them for being stable sooner :)

Almost, I still need const_waker for optimal performance, might be able to simulate it with some unsafe
