Struct JsStatic 

Source 
pub struct JsStatic<T: 'static> { /* private fields */ }
👎Deprecated: use with #[wasm_bindgen(thread_local_v2)] instead
Expand description

Wrapper type for imported statics.

This type is used whenever a static is imported from a JS module, for example this import:

ⓘ
#[wasm_bindgen]
extern "C" {
    static console: JsValue;
}

will generate in Rust a value that looks like:

ⓘ
static console: JsStatic<JsValue> = ...;

This type implements Deref to the inner type so it’s typically used as if it were &T.
