Hey
I updated Rust but didn't change anything in my code. Suddenly I get a bunch of errors in code I didn't even write.
Most of the errors are of this type:
error[E0308]: mismatched types

2065 | let rs = Limb::BITS - s;
| ^ expected `u32`, found `usize`
All errors:

error: aborting due to 27 previous errors
Some errors have detailed explanations: E0277, E0308.
For more information about an error, try `rustc --explain E0277`.
error: could not compile `lexical-core`
To learn more, run the command again with --verbose.
warning: build failed, waiting for other jobs to finish...
error: build failed
I think this is an error in Rust itself or in the library lexical-core. How do I fix it?
Thanks!
