I'm not exactly sure, but I think something may have gone wrong when installing rust and/or adding the target.
https://soroban.stellar.org/docs/getting-started/setup
can you try
rustup target add wasm32-unknown-unknownand see if that helps?

❯ rustup target add wasm32-unknown-unknown
info: component 'rust-std' for target 'wasm32-unknown-unknown' is up to date

Do you have the whole code? Can you share a github repo?

Err and Ok are identifiers defined by libcore, the core part of the standard library that is always available. If there are compile errors relating to those types, it is usually because something isn't quite right with the rust installation.

Others who have reported seeing that error have had it go away after reinstalling Rust.
