| |
| This is an example of a `requestAnimationFrame` loop using the `web-sys` crate! |
| It renders a count of how many times a `requestAnimationFrame` callback has been |
| invoked and then it breaks out of the `requestAnimationFrame` loop after 300 |
| iterations. |
| |
| ## `Cargo.toml` |
| |
| You can see here how we depend on `web-sys` and activate associated features to |
| enable all the various APIs: |
| |
| ```toml |
| {{#include ../../../examples/request-animation-frame/Cargo.toml}} |
| ``` |
| |
| ## `src/lib.rs` |
| |
| ```rust |
| {{#include ../../../examples/request-animation-frame/src/lib.rs}} |
| ``` |
