| # Cargo Features in `web-sys` |
| |
| To keep `web-sys` building as fast as possible, there is a cargo feature for |
| every type defined in `web-sys`. To access that type, you must enable its |
| feature. To access a method, you must enable the feature for its `self` type and |
| the features for each of its argument types. In the [API documentation][], every |
| method lists the features that are required to enable it. |
| |
| For example, [the `WebGlRenderingContext::compile_shader` function][compile_shader] requires these features: |
| |
| * `WebGlRenderingContext`, because that is the method's `self` type |
| * `WebGlShader`, because it takes an argument of that type |
