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}}
|
||
|
|
```
