Old slab version in dependencies breaks build #131
Description
async-executor has a dependency on a really old version of slab.
slab = "0.4.4"
The problem is that this version no longer compiles with any remotely recent version of Rust:
error[E0015]: cannot call non-const fn `Slab::<Waker>::new` in constant functions
--> /home/robin/.cargo/registry/src/index.crates.io-6f17d22bba15001f/async-executor-1.13.1/src/lib.rs:693:32
|
693 | active: Mutex::new(Slab::new()),
| ^^^^^^^^^^^
|
= note: calls in constant functions are limited to constant functions, tuple structs and tuple variants
This was fixed back in 2022 and shipped with slab 0.4.7.
