error: `core::slice::<impl [T]>::len` is not yet stable as a const fn #163

Closed dazzag24 closed 4 years ago

I installed rust this morning with:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

This installed these versions:

darreng@DazXPS:~/code/rust/smol/examples$ rustc --version
rustc 1.38.0 (625451e37 2019-09-23)
darreng@DazXPS:~/code/rust/smol/examples$ cargo --version
cargo 1.38.0 (23ef9a4ef 2019-08-20)

Clone smol and attempt to run an example:

darreng@DazXPS:~/code/rust$ git clone https://github.com/stjepang/smol.git
