Closing, it sounds like you need to install the 32-bit compiler libraries and headers for your system. I think that on ubuntu you can find this in the You can also not configure a cross compiler by just running |
…archo [`unnecessary_to_owned`]: catch `to_owned` on byte slice to create temporary `&str` Closes rust-lang#11648 Detects the pattern `&String::from_utf8(bytes.to_vec()).unwrap()` and suggests `core::str::from_utf8(bytes).unwrap()`, which avoids the unnecessary intermediate allocation. I decided to put this in the existing `unnecessary_to_owned` lint (rather than creating a new lint) for a few reasons: - we get to use some of its logic (for example, recognizing any of the functions in the `to_owned` family, e.g. `to_vec`) - the actual inefficient operation that can be avoided here is the call to `.to_vec()`, so this is in a way similar to the other cases caught by `unnecessary_to_owned`, just through a bunch of type conversions - we can make this more "generic" later and catch other cases, so imo it's best not to tie this lint specifically to the `String` type changelog: [`unnecessary_to_owned`]: catch `&String::from_utf8(bytes.to_vec()).unwrap()` and suggest `core::str::from_utf8(bytes).unwrap()`
