Trait quick_js::Callback

pub trait Callback<F>: RefUnwindSafe {
    fn argument_count(&self) -> usize;
    fn call(
        &self, 
        args: Vec<JsValue>
    ) -> Result<Result<JsValue, String>, ValueError>;
}

The Callback trait is implemented for functions/closures that can be used as callbacks in the JS runtime.

Required methods

fn argument_count(&self) -> usize

fn call(
    &self,
    args: Vec<JsValue>
) -> Result<Result<JsValue, String>, ValueError>
