error: getting the inner pointer of a temporary `CString`
--> $DIR/lint-temporary-cstring-as-ptr.rs:7:48
|
LL | let s = CString::new("some text").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
note: the lint level is defined here
--> $DIR/lint-temporary-cstring-as-ptr.rs:2:9
