The ffi function wrapper need to be changed because in the 2021 edition, when the capture is moved into the closure, it moves the individual field instead of the whole wrapper. But we need to move the whole wrapper because the Drop of the wrapper will delete the C++ closure, and we don't want to call the closure after it is deleted. |

Tutorials
The source code for the Rust and C++ versions of the Memory Game tutorial are located in
the respect rust and cpp sub-directories. They are built using mdbook.
Requirements
Building the tutorial requires mdbook, which you can install with cargo:
cargo install mdbook
Building
To build the tutorial, go into either the rust or cpp sub-directory and run:
mdbook build
The output will be in the book/html subdirectory. To check it out, open it in your web browser.
Code Samples
The code in the tutorial is available in separate steps in .rs and .cpp files.
The .rs files are mapped to different binaries, so you if you change into the rust/src
sub-directory, then cargo run will present you with binaries for the different steps.
The .cpp files are built using cpp/src/CMakeLists.txt, which is included from the top-level
CMakeLists.txt.
