Struct JsNullish 

pub struct JsNullish(/* private fields */);

Implementations

impl JsNullish

pub fn into_nullable_ref<T>(&self) -> &JsNullable<T>

pub fn into_nullable<T>(self) -> JsNullable<T>

Methods from Deref<Target = JsValue>

pub fn browser(&self) -> &Browser

pub fn retrieve_json(&self) -> RetrieveFuture<'_, Value>

Retrive this value from the JS side to the Rust side. Returns Future whose output is a serde_json::Value.

async fn example(input: &HTMLInputElement) {
    let _val = input.get_value().retrieve_json().await;
}
