# `js_namespace = blah`
|
||
|
|
|
||
|
|
This attribute indicates that the JavaScript type is accessed through the given
|
||
|
|
namespace. For example, the `WebAssembly.Module` APIs are all accessed through
|
||
|
|
the `WebAssembly` namespace. `js_namespace` can be applied to any import
|
||
|
|
(function or type) and whenever the generated JavaScript attempts to reference a
|
||
|
|
name (like a class or function name) it'll be accessed through this namespace.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
#[wasm_bindgen]
|
||
|
|
extern {
|
||
|
|
#[wasm_bindgen(js_namespace = console)]
|
||
|
|
fn log(s: &str);
|
||
|
|
}
|
||
|
|
|
||
|
|
log("hello, console!");
|
||
|
|
```
|
||
|
|
|
||
|
|
This is an example of how to bind `console.log` in Rust. The `log` function will
|
||
|
|
be available in the Rust module and will be invoked as `console.log` in
|
||
|
|
JavaScript.
