| error: getting the inner pointer of a temporary `CString` |
| --> $DIR/lint-temporary-cstring-as-param.rs:9:45 |
| | |
| LL | some_function(CString::new("").unwrap().as_ptr()); |
| | ------------------------- ^^^^^^ this pointer will be invalid |
| | | |
| | this `CString` is deallocated at the end of the statement, bind it to a variable to extend its lifetime |
| | |
| = note: pointers do not have a lifetime; when calling `as_ptr` the `CString` will be deallocated at the end of the statement because nothing is referencing it as far as the type system is concerned |
| = help: for more information, see https://doc.rust-lang.org/reference/destructors.html |
