 You can view the list of recovered strings and their addresses in the Log window.

-The plugin will also create a new `RustStringSlice` type, for any strings defined in read-only data sections that are made up of a pointer to string data + the length of that string data. You can view all created strings of this type by examining cross-references to the `RustStringSlice` type.
+The plugin will also create a new `&str` type, for any strings defined in read-only data sections that are made up of a pointer to string data + the length of that string data. `&str` is a Rust primitive type called a "string slice", and is the type used in Rust for string literals ([docs](https://doc.rust-lang.org/std/primitive.str.html)).
