Hello
The clone (or fork) you have seems to have an older version of FLTK (the C++ library) which added the style_buffer() method.
You can try (from the project root):

cargo clean
cd fltk-sys/cfltk/fltk
git pull
cd ../../..
cargo run --color=always --package fltk --example animations

Or reclone the fltk-rs repo.
