-struct Slice {

-/// Helper function to construct a slice vector from the provided argument
-/// array. A slice basically consists of a pointer to the data and the length of
-/// it.
-///
-/// ## Examples
-/// ```cc
-/// auto slice = create_slice({ "hello", "world" });
-/// ```
-///
-/// The `slice` will look like the following:
-///
-/// ```cc
-/// vector<Slice>(
-///     Slice { .ptr: hello_ptr, .size: hello_size },
-///     Slice { .ptr: world_ptr, .size: world_size }
-/// )
-/// ```
